Pneumatics Kit on the Road in Portland Oregon

June 17, 2013

5th Grader Tyler Mapes of Portland Oregon is fascinated by fluid power. Having had some experience building a hydraulic robotic arm from syringes, dowels and tubing for last year's school science fair, he was ready to try something different this year.  After finding information on the CCEFP website about the Hands-on Pneumatics Workshop, Tyler's mom contacted the CCEFP.  Tyler wanted to know if he could get a parts list to build his own Pneumatic demonstrator. Given that some of the components are difficult to acquire in single quantities, Professor Will Durfee instead sent Tyler one of the demonstration kits that had been built by the graduate students working on the original Pneumatics Workshop project.  Once received, Tyler had to assemble all of the parts into a working model. When the assembly was complete, a switch connected to a circuit used a pneumatic cylinder to send a ball into the air, while a second cylinder simultaneously extended a cup to catch the ball. Tyler successfully demonstrated the pneumatics kit at the 2013 Atkinson Elementary School Annual Science Fair.

Through the CCEFP's Education and Outreach Program, the Center strives to expose learners of all ages to the simple and fascinating technology of fluid power. Hydraulics and pneumatics is most easily understood when explanation is accompanied by hands-on demonstration. The CCEFP has designed several hands-on apparatus to demonstrate the principles of fluid power, one being the pneumatic ball and cup kit that Tyler used.  The premise of the device is to understand how a pneumatic circuit works by assembling a series of hoses, valves, cylinders and gauges. By making devices like these, it is our goal to ensure that like Tyler, other students will experience the excitement of hands-on fluid power experiments.

He has also been learning Mandarin Chinese and playing piano under the National Music Syllabus system.  Tyler has a keen interest in math and science, wants to be an engineer and is exploring engineering careers through a Saturday Academy camp over the summer. 

 

UIUC wins Parker Hannifin 2012/2013 Chainless Challenge

April 2013

Chainless Challenge Team

A team of students from the University of Illinois at Urbana Champaign was the overall winner of the the 2012/2013 Parker Hannifin Chainless Challenge competition.  The event was held in Irvine, California on April 11-12. The UIUC team competed against nine other universities that had functional entries. These included the University of Minnesota, Purdue University, Illinois Institute of Technology, University of Akron, University of Cincinnati, Western Michigan University, Cal Poly San Luis Obispo, Murray State University, and Cleveland State University. Additional schools were entered into the event but their bikes were not functional at the time of the competition.

The design consisted of an adult tricycle, a Parker fixed displacement pump (F11-5) connected to an 8-speed internal gear hub that allowed for variable gear ratios another F11-5 was used as a motor at the back wheel, and a one gallon Parker accumulator (BA01B3T01A1). A Hydaforce valve manifold, which was controlled remotely from handlebar switches, was used to operate through one of four hydraulic circuits (Direct pump drive, Accumulator charge, Regenerative braking, and Coasting).

The competition included three performance races, evaluations based on midway and final oral presentations and written reports, as well as team interviews on competition day.

Illinois was the only team to place in the top 3 in all three performance races:

  • 2nd in sprint (200 meter straight course)
  • 3rd in efficiency  (maximum distance traveled after stopping and restarting from full stops at 100 m and 200m + efficiency rating based on bike and rider weight and accumulator pressure & volume)
  • 3rd in time trial (8 mile endurance race, four laps around 2 mile track). (anecdotally, only 4 teams finished the time trial race – all others had some failure that eliminated them from finishing)

There were also a number of award categories with cash prizes to the university and/or students. Illinois placed in the following categories:

  • 2nd in Reliability & Safety ($2000 – 25% for 2nd)
2nd in Best workmanship ($1500 – 25% for 2nd)
  • 2nd in Cost Analysis for Prototype vehicle and a Production cost estimates on a volume of 500 vehicles annual ($1500 – 25% for 2nd)
  • 1st in Best Presentation and Paper  ($3500 - 50% for 1st, 80% to student team)
  • 1st in Best overall score ($5000 - 50% for 1st , 80% to student team)

The UIUC team was sponsored by Parker Hannifin, UIUC, and the CCEFP. Donations of valve manifold and valves were also received from Hydaforce.

Student Retreat heads to Sauer-Danfoss

August, 2012

Student Retreat

Students and Staff attended the 2012 CCEFP Student Retreat, held at Sauer-Danfoss in Ames, Iowa on August 7-8.  In attendance were 11 student participants for this two day event.  The group was given an overview presentation on Sauer-Danfoss -- the history, the company as it is now, the technology and its products.  HR representatives then lead our students through a series of team-building exercises with examples of scenarios commonly found working in teams in the real world.  Students were given a facility tour followed by lunch with engineers who are closely aligned and familiar with CCEFP research.  After lunch, the student group left Sauer-Danfass for tours at the Picket Fence Creamery and White Oak Vineyards, both about 30 miles outside of Ames, IA.  Students had an opportunity to learn a bit about dairy farming, milk bottling and the craft of wine making.  That evening, the group met up with Sauer-Danfoss engineers for a group dinner at a local restaurant.  

The following morning, Prof. Jim Van De Ven presented a challenge to students to create and design problem sets for the Fluid Power System Dynamics mini-book, authored by Professors. Durfee and Sun.  Students embraced the challenge and successfully submitted 20 problem sets for consideration into the curriculum module.   The students participated eagerly and also recommended that the Center host a similar exercise on a larger scale, possibly with some sort of competition.  These student submitted problem sets will enhance the existing mini-book and perhaps motivate use by instructors.  In addition, with this model in place, future mini-books may enter the fluid power curriculum pipeline more readily.  Finally, the students got to try out a few CCEFP hands-on outreach activities such as the Science Museum of Minnesota's straw rockets (targeted at younger, school-age kids) and the TeacherGeek Hydraulic Pet Racer (intended for middle school classrooms).  These activities are examples of hands-on demonstrations that CCEFP students and faculty can use when leading K12 outreach events at their home institutions.

This was absolutely a productive event for CCEFP students and Sauer-Danfoss industry members alike.  Partnering with an Industry member is a terrific opportunity for students and in this case, Sauer-Danfoss was also very pleased to host the CCEFP.  It was a rare occasion to have so many students visit their facility and we are certain other member companies would welcome a similar opportunity to showcase their companies.  With continued faculty / student engagement and commitment, more of these events will be possible in the future.
 
If you would like to host CCEFP students for a company tour / workshop in the future, please contact Alyssa Burger.

Director visits Mesabi Wind Turbine Project

December, 2011

Wind energy researchers from UMN visited Mesabi Range Stelson at Wind TurbineCommunity and Technical College (MRCTC) in Eveleth, MN.  The purpose of the visit was to inspect the Vestas V27 225 kW wind turbine that MRCTC recently installed and to discuss its use for potential collaborations.  Both UMN and MRCTC are interested in installing a hydrostatic transmission (HST) in the wind turbine and conducting research. 

MRCTC offers a two year training program for wind turbine technicians and installed the V27 to offer their students hands on experience.  The turbine was purchased used directly from Vestas in Denmark and is designed to operate at 50 Hz AC output.  Some method of converting the output to the 60 Hz power used in the US is needed and an HST accomplishes that plus offers a test bed for research in applying HSTs to wind turbines.  UMN is soliciting support from its industry partners to build, commission, and perform research on the HST.

Participating in the visit from the UMN ME department were Prof. Kim Stelson, Dr. Feng Wang, Rahul Dutta and Brad Bohlmann.  The Saint Anthony Falls Laboratory’s Eolos team was represented by Matt Lueker and Chris Feist.

The photo shows CCEFP’s Director, Prof. Kim Stelson, exiting the tower of the V27 wind turbine at MRCTC.

REU Students' Research Results in new ASTM Standard

November, 2011

On November 30th, ASTM International released ASTM D 7752-11 for publication. The published document is titled “Standard Practice for Evaluating Compatibility of Mixtures of Hydraulic Fluids.” 

Research for this new standard was conducted at the Milwaukee School of Engineering (MSOE) by REU students Emily Schultz (2011), Cedric Harville (2010), Kelsey Whittaker (2009), Daniel Schick (2008) and Ricardo Rivera (2007).  This standard is beneficial when determining the compatibility of fluids, an important consideration when planning to convert to energy efficient and/or biodegradable fluid. 

The standard practice includes a flow chart that prescribes the number of system flushes required as a function of the compatibility test results.  The flow chart was developed by Kelsey Whittaker, the lead author on the publication. Paul Michael, Research Chemist at MSOE,  was the advisor for the students on this research.

More information about ASTM publications is available at their website: www.astm.org

Student Leadership Council Update

July, 2011

Logo

In an effort to improve the effectiveness and focus of the student leadership council (SLC), a student committee has been working this summer to propose changes to SLC operation and structure.  Headed by former SLC president Tim Deppen, the committee has focused on the tasks of proposing new activities and streamlining the SLC structure. Currently the SLC runs the biweekly webcasts which provide students, faculty, and industry members with updates on all sponsored projects, as well as occasional educational and administrative presentations.  In addition, the SLC organizes a student retreat for all CCEFP students each summer to facilitate cooperation and innovation in research and outreach activities.

This year, a proposal has been submitted for education and outreach funds to increase the SLC's effectiveness and participation in the center. First, the committee has asked to have a travel grant fund which will be awarded to students travelling to another university or industry site for project collaboration.  Since travel budgets have been decreasing and are usually prioritized for CCEFP meetings and conference travel, this will help to ensure that student collaboration can continue. Second, the SLC would administer a student project grant program, which would fund education, outreach, or social activities proposed by CCEFP students.  The third proposal is the development of a new student orientation program, under which each new CCEFP student will meet with their appointed SLC representative and also receive information about the center and how his or her project relates to the others in the center.  Further activities are also under discussion for future years.

In addition to these activity changes, the committee has recommended slimming the SLC from two to one member from each university, and compensating four officers with a fund usable for training, equipment, conference travel, or other research and professional activities.  The reduced SLC size will help with meeting scheduling, and the activity fund will both encourage more officer participation, as well as compensate for the increased officer workload.

We are excited about the new opportunities that the SLC will be undertaking!  Finalized plans and organizational changes will be adopted by the SLC when it meets at the annual student retreat August 15th and 16th in Schaumburg, Illinois.

MSOE offers Hydraulics Training to U.S. Navy

July, 2011

Khalil at Navy

Dr. Medhat Khalil (front row, center), director of professional education and research development at CCEFP member institution Milwaukee School of Engineering (MSOE), travelled to the National Maritime Intelligence Center (NMIC) in Washington, D.C. where he taught the "Introduction to Hydraulics” course to sixteen members of the U.S. Navy.

Dr. Khalil offered the class at the NMIC because the attendees wanted to learn more about hydraulics, control systems, and the relationship between hydraulic systems for use in U.S. Navy systems for improved reliability and operation.  Introduction to Hydraulics is a 32-hour seminar designed to acquaint individuals with the fluid power field and provide a practical working knowledge of this important and growing industry.

As a result of completing this course, those naval members are able to identify the distinguishing features of hydraulic systems; apply industry standards to hydraulic and schematic symbols; analyze hydraulic circuits from a schematic drawing using animated schematics modeled by Automation Studio; explain the operation and applications of valves, cylinders, pumps and motors using animation and video clips; identify the chemical and physical properties of fluids as they relate to hydraulic system operation; utilize continuity and energy balance equations; and understand the basic configuration and operation of hydrostatic transmissions.

In commenting on the skills or techniques learned in the course, attendees noted that they “learned how to understand schematics and different types of system components, and how they operate.” Another said they “learned about the workings of and relationships between valves, pumps and accumulators.”

Introduction to Hydraulics is just one of many professional education seminars offered through MSOE’s Fluid Power InstituteTM (FPI) which are endorsed by the National Fluid Power Association (NFPA) through sponsorship and educational partnership. The FPI is one of the leading academic fluid power research laboratories in the U.S., and it conducts research and testing for some of the largest hydraulic companies, as well as system evaluations for the U.S. military. By offering this course at the NMIC, the FPI further expands its relationship with the U.S. military.

UIUC's William King Discusses Surface Microstructures

May 2011

Bill King
In an interview for the University of Illinois Mechanical Science and Engineering website, Professor William King, (UIUC, Project 1D) explains how machining microstructures onto surfaces can change the properties of those surfaces to improve performance in machines.  With the advent of this technology, King says that consumer products are already being dramatically enhanced with better performance and new properties.  Among the examples given, King cites reductions in the amount of energy needed to run some machines due to increased surface area provided by the micro-structured surfaces. Commercialization of this technology is underway through a company co-founded by King in 2008, Hoowaki, LLC.

CCEFP attends IFPE

April 5, 2011

IFPE logo

The CCEFP was well represented at the 2011 IFPE Conference held March 22-26 in Las Vegas.  In addition to conducting it's NSF Site Visit at IFPE, the Center hosted a booth and presented over 40 technical papers in the 52nd National Conference on Fluid Power. 

Co-located with IFPE, the Center held its 5th annual NSF Site Visit, welcoming NSF officials and the accompanying site visit team comprised of experts in various disciplines of fluid power.  Normally held on the campus of the CCEFP's lead institution, the University of Minnesota, the annual site visit allows the NSF to review the progress of the center's overall management as well as its research projects.  However, owing to the impact that the Center's work can and does have on the fluid power industry at large, as well as a bit of fortuitous timing to coincide with IFPE and CONAGG, this year's site visit was shifted to Las Vegas to allow NSF officials the opportunity to witness firsthand the vast industry that the Center's work benefits.   

The CCEFP booth featured hardware displays of the High Efficiency Excavator (TB1), Compact Rescue Robot (TB4) Fluid Power Orthosis (TB6), Hot Gas Vane Motor (Project 2A), Free Piston Engine Compressor (2B.1), Portable Water Hydraulic Excavator (E&O) and the Tiny Fluid Power demo which is associated with Test Bed 6.  The Orthosis was particularly well received by IFPE attendees as the team had prepared a working demonstration both on a test stand and with a human subject.  Prof. Geza Kogler wore the device and walked the show floor, attracting much attention to the project as well as to the Center's booth.  The Excavator and its accompanying informational video also drew quite a bit of traffic and was well staffed by the Purdue student researchers who fielded questions and comments from IFPE attendees.

Additionally, students and faculty of the Center were on hand to present over 40 of the 120 accepted papers for the 52nd National Conference on Fluid Power.

A few photos of the Center's activities at IFPE are available in the Conferences / Events section.

Awards Presented for top Research Posters at IFPE Poster Show

March 22, 2011

Three graduate student researchers were awarded prizes for "Best Poster" during the CCEFP Annual Meeting held March 22-23 at IFPE.  The judging panel was comprised of several CCEFP Industry member representatives and the CCEFP Scientific Advisory Board.  Points were awarded based on content, design, presentation skill and overall effectiveness, with prizes of $100, $250 and $500 awarded for 3rd, 2nd, and 1st places respectively. This was the first time that awards were given during the Center's annual poster show.

The winners were:

1ST PLACE

Josh and Andrew Plummer
Graduate Student Presenter: Josh Zimmerman, Purdue University
Testbed 1: Heavy Mobile Equipment - High Efficiency Excavator
Faculty Advisor: Professor Monika Ivantysynova

Poster Abstract: The excavator test bed serves as a platform for demonstrating research advances throughout the CCEFP.  It is a 5 ton Bobcat 435 excavator, but the stock hydraulic system (load sensing) has been removed and replaced with a displacement controlled hydraulic system.  Results for side by side fuel testing of the new displacement controlled hydraulic system and a standard machine of the same model found 40% fuel savings on average for a truck loading cycle and will be included in the poster presentation.  With the new system architecture all functions are controlled electronically allowing the use of advanced control strategies.  An advanced machine power management control strategy has been implemented on top of the displacement control platform to minimize the fuel consumption of the machine according the working cycle performed.  Simulated and measured results for this control algorithm will be presented.  The improved efficiency offered by displacement controlled technology has led to lower working temperature for the hydraulic fluid.  A thermal model of the hydraulic system has been developed to simulate working temperatures and to aid in specifying the cooling requirements for the new hydraulic system.  Finally, a feasibility study for a hybrid displacement controlled hydraulic system, allowing energy recovery and engine load leveling, will also be presented.

2ND PLACE

John Tucker and Andrew Plummer

Graduate Student Presenter: John Tucker, Vanderbilt University
Project 2C.2: Advanced Strain Energy Accumulator
Faculty Advisor: Professor Eric Barth

Poster Abstract:  Hydraulic accumulators are energy storage devices commonly used to provide supplementary fluid power and absorb shock. One particularly interesting recent application of these devices is regenerative braking in hybrid vehicles. The purpose of this research is to investigate a new method of storing energy particularly suited for use in Hydraulic Regenerative Braking (HRB). Specifically, this project’s objective is to design a low cost, minimal maintenance, high energy density accumulator for implementation in a fluid powered automotive regenerative braking system in a hydraulic hybrid vehicle. The advocated technique involves using strain as the mechanism for energy storage, as opposed to the compression of gas in typical gas-charged accumulators. However, by using a high energy density elastomer and a geometry that differs from conventional spring-piston accumulators, the proposed accumulator addresses some of the weaknesses of its traditional counterparts.


3RD PLACE

Kelly Burgess and Andrew Plummer

Graduate Student Presenter: Kelly Burgess, Milwaukee School of Engineering
Project 1G.1: Tribofilm Structure and Chemistry in Hydraulic Motors
Advisor: Paul Michael, Research Chemist

Poster Abstract: This poster presents an investigation of the fluid properties that affect starting efficiency in hydraulic motors. Starting motor efficiency is an important design consideration because it often determines the pump horsepower and the minimum motor displacement in mobile hydraulic systems.  Five hydraulic fluids have been tested and evaluated in a large-scale hydraulic dynamometer.  The boundary friction, mixed-film lubrication, thermophysical, and pressure-viscosity properties of these prototype fluids have been characterized. These hydraulic fluids have been evaluated in geroler, axial piston, and radial piston motors under starting conditions in accordance with the ISO 4329-2 standard test method.  Correlations between starting efficiency and fluid boundary friction, traction,thermophysical and pressure-viscosity coefficients have been identified.  The results indicate that startability improves with decreasing boundary friction coefficient, decreasing pressure-viscosity coefficient, and increasing thermal conductivity. The relative impact of these fluid properties varied with motor design.

Congratulations to the three winners and to all the students who produced very high quality posters for this year's show!

Portable Powered Ankle Foot Orthosis (PPAFO) Demonstrated

February 12, 2011

Test bed 6, the Portable Powered Ankle Foot Orthosis (PPAFO) was recently successfully demonstrated to provide functional assistance on two individuals with lower leg weakness. One participant suffered from plantarflexor (calf muscle) weakness due to a spinal injury and could no longer generate torque at the ankle to push his toes down. This impairment affected his ability to propel himself forward while walking - thus making extended walking an exhausting task. The other individual had a form of muscular dystrophy, a disorder that caused weakness in both the calf and shin muscles, i.e., both plantarflexor and dorsiflexor muscles. Dorsiflexor impairment can limit the ability to pull the toes up during swing - thus creating a potential tripping hazard.

During testing, the PPAFO was able to provide functional assistance to both subjects. Although the PPAFO was not capable of providing enough power to fully restore normal propulsive torque, it was able to generate modest power for propulsive assistance. For the individual with plantarflexor weakness, this added plantarflexor torque resulted in increased single leg support time on the assisted side and demonstrated a more normal ankle motion. For the individual with dorsiflexor weakness, the PPAFO also successfully controlled the motion of the foot during swing. This assistance eliminated a potential tripping hazard by keeping the toes from contacting the ground. These experimental results demonstrated that the PPAFO was capable of providing untethered functional assistance for people with walking disabilities.

Researchers at several of the CCEFP institutions (University of Illinois, University of Minnesota, Milwaukee School of Engineering, Georgia Institute of Technology, and North Carolina A & T) are working on the development of the next generation AFO that will push the limits of fluid power technology. These innovative projects will lead to the development of a miniature and integrated power supply, actuators, valves, transmission lines and housing, while also addressing specific issues related to the development of novel powered exoskeletons to assist persons with disabilities.

CCEFP group visits NREL Wind Technology Center

October 22, 2010

wind turbine

As announced in previous news, the CCEFP is actively pursuing research into the use of fluid power applications for wind energy.  Specifically, the CCEFP is proposing the use of hydrostatic transmissions for wind energy turbines. In support of this interest, on September 30, a group from CCEFP and the University of Minnesota visited the National Renewable Energy Laboratory's (NREL) National Wind Technology Center (NWTC) in Boulder, Colorado.  Included in the group were Dr. Kim Stelson, CCEFP Director and University of Minnesota (UMN) Professor; Dr. Arne Kildegaard, UMN-Morris Professor; Mike Gust, CCEFP Industry Liaison Officer;  Brad Bohlmann, CCEFP Sustainability Director and UMN Adjunct Associate Professor.

The CCEFP group met NREL and NWTC researchers to learn more about their program, discuss topics of mutual interest, and tour the facilities.  Dr. Stelson gave a presentation to NWTC personnel on CCEFP and UMN's interests in wind research.  The presentation covered the $8M wind energy grant that a UMN-led team recently received from DOE and provided an overview of our interest in doing research on applying and optimizing an HST driveline to a wind turbine in order to improve wind turbine reliability and efficiency.

NREL has approximately 10 turbines from different manufacturers ranging in size from 2.25 MW to 600kW which are used for testing, research, and commercialization.  Some are from manufactures who no longer produce wind turbines, so NREL is free to make changes to them without restriction.  In addition to turbine blade testing facilities, NREL has a 225kW dynamometer and a 2.5 MW dynamometer in place, with an additional 5 MW unit planned for installation.  NREL also instituted a "gearbox reliability collaborative" approximately 2 years ago, with membership available by monetary or in-kind commitment.

The group also met with faculty at Colorado School of Mines and University of Colorado at Boulder.  These schools, along with Colorado State University and a number of industry members, formed the Center for Research and Education in Wind (CREW) in 2009.  The potential for future collaboration in wind energy research will be explored by both parties.  Dr. Stelson was invited as a guest presenter to a group of CREW researchers, PIs, and members. Approximately 20 people attended either in person or via webcast.

Professor Book presented the following lecture:

Title: Cold Cases and Hot Topics

Abstract: Where are the promising research areas of today and yesterday? Surely there are the exciting areas of Bio-Nano-Info Technologies, the "hot topics" in research today, but along with them can be found some "cold cases", topics that were too hard to solve, or were thought to be solved, in the past. Some topics, such as energy supply, are solved again and again and likely will be for the foreseeable future to come. Several of these cold cases will be reviewed and explored. Can they again be hot topics? Topics that have reemerged and again matured, topics that are now reemerging, and topics that may soon reemerge will be considered. Researchers, young and old, as well as funding agencies are always looking for promising topics for their resources of time and funds. Should they consider these cold cases readdressed in light of new results from hot topics. Specific research results presented in these areas from personal experience and observation.

Prof. Perry LiProf. Terry SimonProf. Eric LothProf. James Van de Ven

Professor Perry Li (CCEFP Deputy Co-Director) has been awarded a research grant from the National Science Foundation (NSF) to develop a "Novel Compressed Air Approach for Off-Shore Wind Energy Storage".  The four year, $2 million award is made through the Emerging Frontier in Research and Innovation (EFRI) and the Grant Opportunities for Academic Liaison with Industry (GOALI) programs.

The investigators of the research are: Perry Li (PI) and Terry Simon (Co-PI) at the University of Minnesota, Eric Loth at the University of Virginia, James Van de Ven at the Worcester Polytechnic Institute and Oakland CA based industry partner, Lightsail Energy. The research proposes to develop a localized method for storing off-shore wind energy before conversion to electricity in high pressure compressed air vessels.  In addition to allowing the storage of wind energy during periods of low demand, the concept will achieve load leveling so that components can be down-sized for average rather than peak power.  The concept makes use of the comparative advantages of hydraulics and pneumatics in a so-called "Open Accumulator" architecture, and an isothermal air compressor/expander design.  The interdisciplinary research involves fluid flow, heat transfer, machine design and systems and control.

Robotics Curriculum to reach more American Indian Students

 

February 15, 2010

students with robot

The CCEFP Education & Outreach Pre-College education program reports several exciting developments in the ongoing partnership with the American Indian educational programs: 

Local schools who partner with the gidakiimanaaniwigamig (gidaa) program have launched robotics curriculum in their day curriculum and after-school programs. These programs are currently being taught at the Albrook School and the Ojibwe School.  In the future, a community robotics program for youth will be launched as well.  Information about the Albrook School's programs can be found at the following links:

Grades 3-4 STEM Lego Robotics
Grades 7-12 STEM After School Robotics
Constructing a Robot blog 

The Albrook School, a key partner with CCEFP, is reorganizing to better align with the goal of moving students towards STEM fields.  The school is piloting its day-time robotics curriculum and in the future, anticipates a formal cooperation with Fond du Lac Tribal and Community College in which students could earn college course credit for completion of robotics programs.  Fond du Lac Tribal and Community College is also in the initial stages of offering a pre-engineering program.

Also of note: The gidakiimanaaniwigamig website has recently undergone a thorough redesign.  The updated website includes information on the gidaa camps, science fairs, robotics/fluid power activities and the new manoomin (wild rice) project.

The technology-driven direction taking place in the Cloquet area is directly linked to the Center's relationship with gidaa. The CCEFP's promotion of Robotics curriculum has been key in exposing gidaa students to technology, engineering concepts, the scientific method and critical thinking skills.

CCEFP Plans for Future Self-Sustainability

January 19, 2010

opportunity image

Like all ERCs, a primary challenge facing the CCEFP is sustainability, or, the continuation of CCEFP research, educational and outreach efforts after NSF funding has ended. We are currently in Year 4 of CCEFP operation. Our core funding for next year and through Year 8 (May 2014) will continue at current levels. Funding will then be reduced to two thirds of this level in Year 9 and one third of this level in Year 10. In Year 11, beginning June 2016, we will no longer receive any NSF or university matching funds.

The sustainability challenge is to continue to operate while being weaned of NSF and university funds. The track record of previous ERCs proves that approximately two thirds of them have successfully made this transition. Previous transitions, however, have always been challenging, requiring difficult choices due to the changing funding picture. The key to success is to anticipate and take actions to counteract the transition early since the funding cutoff is so drastic.

The CCEFP is actively pursuing a plan for the transition to sustainability. We recently created a new part-time position, CCEFP External Funding Director, to develop research funding opportunities and have hired Brad Bohlmann to fill that role. Brad is an excellent choice given his solid track record of attracting external research funding while working in the fluid power industry.

We have also formed the CCEFP Sustainability Task Force to create a plan which will guide us through the transition.  The task force will have it's first meeting in late January.  Members are:

  • Kim Stelson, University of Minnesota, Chair
  • Andrew Alleyne, University of Illinois, Urbana-Champaign
  • Wayne Book, Georgia Institute of Technology
  • Tom Bray, Milwaukee School of Engineering
  • Mike Gust, University of Minnesota
  • Ed Howe, Enfield Technologies
  • Monika Ivantysynova, Purdue University
  • Joe Kovach, Parker-Hannifin
  • Eric Lanke, National Fluid Power Association
  • Lonnie Love, Oak Ridge National Laboratory
  • Bill Parks, Deltrol Fluid Products

With these actions it is our goal to establish a clear strategy and move forward confidently into the future of Fluid Power Research.

 

CCEFP Receives Renewal and Major Funding

January 8, 2010

NSF Logo

The National Science Foundation (NSF) has announced that it will award the Engineering Research Center for Compact and Efficient Fluid Power (CCEFP) a four year, $16 million dollar grant, enabling the Center to continue its efforts in transforming fluid power—how it is researched and taught. Industry partners will augment NSF funding with cash and in-kind contributions, and the Center’s seven universities will contribute an additional $3.2 million.

This is welcome news to the more than 30 faculty, 300 undergraduate and graduate engineering students, 2500 K-12 students and the 57 industry sponsors who have been involved in the CCEFP since its founding in 2006 through an initial NSF grant. Their work on four test beds and over 25 research projects focuses primarily on increasing the efficiency of existing fluid power applications; expanding the use of fluid power in transportation; creating portable, un-tethered human-scale fluid power applications; and assuring that fluid power is clean, quiet, safe and easy to use. Results are already impressive with 14 inventions disclosed and over 100 technical papers published.

The Center’s education and outreach program is equally ambitious, with over 20 projects designed to:

  • attract our nation’s pre-college students to science and engineering generally and to hydraulics and pneumatics in particular
  • educate all mechanical engineering undergraduate students about fluid power, raise the general public’s awareness of the ubiquity of fluid power,
  • increase the diversity of students and practitioners in fluid power research and industry,
  • establish lasting forums where industry and academia can exchange ideas and strategize. 

“The CCEFP has already made a major impact,” according to Dr. Kim Stelson, Center Director.  “The Center has transformed hydraulic and pneumatic research in this country from isolated efforts by a few to a cohesive, strategically-directed collaborative team linking seven universities and many leaders in the fluid power industry. Recognition of these efforts continues to grow, as the Center’s work impresses academic and engineering audiences worldwide. Our efforts in education and outreach show significant results, too, as the CCEFP works with established, effective partners to maximize program impact.”    

“The synergy of the CCEFP is particularly impressive,” says Dwight Stephenson, HUSCO International, Chairman of the Center’s Industry Advisory Board.  The cooperation between the research teams and industry, facilitated through the Center’s network of researchers, educators and industry, is accelerating the rate of fluid power technology development. The CCEFP is a catalyst for  this positive change and growth.” 

The CCEFP is one of 15 NSF-funded Engineering Research Centers charged with conducting pioneering research in emerging technologies and in training the next generation of engineers to be leaders in innovation.

CCEFP Hosts NFPA Fluid Power Challenge

December 10, 2009

Fluid Power Challenge winners

The CCEFP hosted the National Fluid Power Association's Fluid Power Challenge, a competition that gets middle school students excited about fluid power. A Workshop Day for the event was held at the University of Minnesota campus on November 5,  followed by the Challenge Day on December 10, 2009.

During the Fluid Power Challenge, middle school students learn about fluid power technology (hydraulics and pneumatics) and gain hands-on experience while building a fluid power mechanism with real world applicability. The program is designed to introduce the students, and their teachers, to the world of engineering and fluid power careers.

On Challenge Day, 22 8th-grade teams (four students per team) designed and built fluid power mechanisms that pick an object from one platform, rotate and place it on another. In addition to the number of pick-and-place cycles a school’s machine completes, a review of each team’s design approach, teamwork and portfolio were used in the final evaluation.

A student from a past competition said “This opens up more opportunities for engineering and careers kids aren’t aware of. It’s fun...you get to work with other kids and learn more math and science.”

Through the Challenges, the National Fluid Power Association (NFPA) and the Center for Compact and Efficient Fluid Power (CCEFP) hope to encourage students to select more mathematics and science courses in their high school curricula to keep their options open for technology-based post-secondary studies.

A video of a winning team’s fluid power mechanism in action is available at the Center's YouTube site:

New Associated Projects Announced

December 7, 2009

Wind Turbines     Surgical Team

Two new, large-scale CCEFP associated projects have recently been announced:

  • The University of Minnesota has been awarded an $8 million wind power research center, funded by the Department of Energy (DOE). The major fluid power component of this project is the development of hydrostatic power transmission technology for wind power, a collaborative effort between the University of Minnesota and Eaton Corporation.
  • Vanderbilt University has received a major contract for new research from the Martin Companies to investigate the use of miniaturized fluid power in medical Magnetic Resonance Imaging (MRI) applications. This research will develop miniature MR-compatible fluid-power actuation that offers no distortion to the image. Fluid power is one of only a few forms of actuation that has the potential for 100% MR compatibility.

Current CCEFP research focuses on four test beds spanning five orders of magnitude of power and weight: an excavator, a hydraulic hybrid passenger vehicle, a rescue robot and an orthosis. The Center plans to expand into even larger and smaller applications—wind power in the 1 MW range and medical micro-robots in the micro-watt range. These two new initiatives give us the ability to expand CCEFP research into the larger and smaller regimes.

 

CCEFP Faculty Member Awarded NSF Major Research Instrumentation Grant

December 1, 2009

Professor Sun

CCEFP faculty member Professor Zongxuan "Sunny"  Sun (University of Minnesota) was recently awarded an $800,000 NSF MRI (Major Research Instrumentation) grant. The grant will enable CCEFP to construct a hydrostatic dynamometer. Because of the superior power to weight ratio of hydraulics, a hydrostatic dynamometer will have a much lower moment of inertia than a conventional electric dynamometer. This allows the hydrostatic dynamometer to have a higher speed-of-response allowing it to simulate realistic engine transients. Understanding how an engine behaves during these rapid transients will provide important unknown information on fuel economy and emissions. The hydrostatic dynamometer will be an essential research tool for optimizing the control approach for the Hydraulic Hybrid Passenger Vehicle (HHPV) test bed.

2009 Annual Meeting Report

November 5, 2009

The 2009 CCEFP Annual Meeting took place October 7-9 at the Alumni Foundation Center of North Carolina A&T State University.  Over 130 members including 25 industry representatives were on hand to witness the presentations and participate in the poster shows and breakout sessions.  This was the first year of a new format that included breakout sessions of smaller groups that enabled participants to more easily discuss the topic and ask questions.

Attendees took a tour of some of the engineering facilities on the campus, which included the labs used by CCEFP students and faculty.  In the labs focusing on human machine interface, we were given a demonstration of some of the work being done on interaction with the excavator and rescue robot test beds.  Students were able to demonstrate their analysis of the tasks involved in driving an excavator and showed a simulation of a virtual excavator being operated with a Phantom controller.  Also on display were some of the impressive facilities used for material science and material testing, including lab space for the new Center for Advanced Materials and Smart Structures.  Other highlights of the tour included research on driving simulations, air traffic control interfaces, augmented reality, military task allocation, and flow visualization.

Following Thursday’s dinner banquet, attendees were treated to a cultural performance of West African traditional dancing as performed by NCAT’s own E. Gwynn Dancers.  The group consists of approximately 20 NCAT students studying traditional African dance under the direction of Dr. Eleanor Gwynn.  While part of the group, students have the opportunity to travel to Africa to learn dance techniques first hand from traditional performers.  Attendees at Thursday’s dinner witnessed three distinct dances and were even encouraged to join in on for the last dance. A fair number of CCEFP members were good sports and heeded the call of the dancers to take part.

Title:  Numerical Model for a Hydraulic In-line Silencer

Abstract:  It is proposed that an in-line hydraulic silencer with a particular engineered lining can provide an effective alternative to other current silencing technologies.  As a first step in validating this hypothesis, and to help with the design process, a numerical model is developed for a hydraulic silencer.  The silencer consists of an annular dispersive medium with a rigid outer boundary, where fluid flow is directed through the annulus.  Silencer characteristics, including input port impedance and acoustic transmission loss, are predicted by this model.  Effects of silencer geometry and material properties, including nonlinearities, are discussed.

Industry's participation concluded with an open mic discussion on how students and industry can be more engaged, such as stronger collaboration with research project champions to student internships to full-time employment opportunities. Industry gave an informal presentation on hot topics within the field and welcomed student feedback and inquires. Other items on the agenda were beautiful campus tours, a formal SLC meeting and a FIRST Pneumatics Outreach activity.

A warm thank you to our industry representatives who attended the meeting, a hearty congratulations to the SLC for another fine retreat, and to UIUC for kindly hosting this event!

 

CCEFP 2008 Annual Meeting held at MSOE

IMG_0793.jpgThe Center held its 2nd Annual Meeting at the Milwaukee School of Engineering, May 28 - 30, 2008. The agenda included a warm greeting from Hermann Viets, President of MSOE and Tom Bray, Dean of Applied Research. Professor Kim Stelson, Director of the CCEFP welcomed over 165 industry members, faculty, staff and students.

Throughout the two and one-half day meeting all research and education projects were presented. Project presentations were informative and clearly articulated progress to this point and anticipated future work. The audience was also given an opportunity to exchange dialogue with the presenters during the question and answer sessions.

Positive critique and inquisitive questions sparked further conversation into the Student Poster Session and Reception, where all students were invited to present their research within the CCEFP. The poster session allowed for more in-depth discussions with individuals on both sides of the show.

A highlight of this year1s meeting was the Industry and Student Dinner Dine-Around. Seven industry members sponsored a dinner for students and industry to mingle together in a light-hearted atmosphere. We would like to thank the following industry members for sponsoring that event: Evonik Rohmax USA, Inc., Eaton Corporation, Gates, HUSCO, Parker Hannifin, RT Dygert and Sauer-Danfoss.

Meeting participants woke early to enjoy bacon and eggs along with a lesson on the fluid flow in a servo-valve. Following the coloring book activity, the meeting resumed with additional research and test bed presentations. Mr. Mike Gust of the CCEFP presented valuable information on intellectual property and the roles of the Center in relationship to its industry members. Prof. Will Durfee presented the Center1s education and outreach initiatives. The Milwaukee School of Engineering kindly hosted a reception at the new Grohmann Museum where attendees were able to view the rooftop sculpture garden that rose high above the building that housed many forms of industrial artwork.

The concluding day of the meeting allowed for advisory boards to meet together in person to share thoughts and have discussions on the Center for Compact and Efficient Fluid Power. A highly anticipated panel discussion lead by industry representatives on their personal careers paths and guidance for our future fluid power academics and industrial leaders prompted much discussion between the panel and students in the audience. This year's meeting was very fruitful and sparked more enthusiasm among the CCEFP leadership, students and the Center1s industry members. The Center invited the members of the Scientific Advisory Board (SAB) who serves as an external committee to review and evaluate the Center in its current state. The Center continues to welcome feedback on its strategic direction through the SAB and its industrial partners.

 

FIRST Robotics Competition Team

The CCEFP sponsored a team of 20 high school students from the Fond du Lac Indian Reservation community in the midwest regional FIRST Robotics competition held at Williams Arena March 27-29.

FIRST stands for "For the Inspiration and Recognition of Science and Technology", and the competition was the first of its kind ever held on the University campus.

The competition started with a 15-second programmed run around the track which each robot made unassisted. Next, the robots earned points by hoisting balls over a ladder in the middle of the track and then crossing a finish line.

After the initial round of robotic competition, alliances were formed between two or three robot groups to create teams. Groups forming the team alliances exchanged and combined strategies to develop the most efficient means of competing with other teams. The team with the most points after the match ended went on to further competition with the top rated alliance traveling to Atlanta next month for the national championships.

The CCEFP sponsored and mentored the anishinaabeg ogichidaag FIRST Robotics Team formed by students from a group of schools near Cloquet, MN. As first-time competitors, they were excited to be part of the event, and they came away from the experience with a greater understanding of how to succeed in future competition.
