NFPA Research Supplement Update: Individual Electro-Hydraulic Drives for Off-Road Vehicles

I recently attended the October 2018 Summit of the Center for Compact and Efficient Fluid Power (CCEFP) at the University of Minnesota. This is one of the meetings this fiscal year where the fluid power research projects supported by our new NFPA Research Supplement Program were presented.

In our efforts to increase the number of university students educated in fluid power, the NFPA Education and Technology Foundation has provided ten $10,000 research supplements to ten academic faculty members working on fluid power research at six universities. This helps to engage current and build the careers of future university faculty who are and will be in a position to teach fluid power to undergraduate engineers on their campuses. The research supplements provide travel support so that each faculty member and one of their graduate students can attend to present their research at designated industry conferences and research summits like the one hosted by the CCEFP.

One such faculty member is Professor Andrea Vacca of Purdue University, who presented on his project, “Individual Electro-Hydraulic Drives for Off-Road Vehicles,” at the CCEFP Summit. The goal here is to develop and demonstrate an electro-hydraulic technology that, with respect to current state-off art solutions for off-road vehicles, can lower power consumption of the fluid power system, reduce noise and vibrations, allow for “zero emission” operation of the vehicle (engine off), and enable “smart actuators,” operating as modern “plug & play” elements with integrated control and self-diagnostic functions. Working with funding provided by the U.S. Department of Energy, Vacca and his team, which includes industry partners Bosch Rexroth and CNH, are focusing on the use of electro-hydraulic actuators (EHAs) and designing a new, 4-quadrant electro-hydraulic pump. Once prototyped, the new technology will allow for the development of self-contained electro-hydraulic modules that can be demonstrated on an actual piece of off-road equipment.

A copy of Vacca’s presentation slides can be accessed here.

Collectively, the research projects supported by NFPA Research Supplements represent more than $4.9 million in funding from a variety of organizations, including the U.S. Department of Energy, the National Science Foundation, and the Center for Compact and Efficient Fluid Power (CCEFP). They are an excellent sample of the growing body of fluid power research being funded by the federal government and other research organizations.
