NFPA Showcases Latest Fluid Power Research for Off-Road Vehicles

SOURCE: NFPA | January 20, 2020

The National Fluid Power Association invites you to attend the IFPE Research Symposium on March 11, 12, and 13. Lunch is on us. Over these three days, we will present a program that showcases the latest fluid power research being performed at U.S. universities with funding provided by a new program within the U.S. Department of Energy to improve the energy efficiency of hydraulic systems on off-road vehicles.


Our three distinguished presenters are:

Wednesday, March 11

11:30 a.m. to 12:30 p.m.

Room S231

Individual Electro-Hydraulic Actuators for Off Road Machines

Andrea Vacca, Purdue University

The objective of the project is to propose a new technology for electro-hydraulic drives for machines. The project sub-goals are to develop and test a novel electro-hydraulic pump/motor, to develop a layout architecture for electro-hydraulic actuators, and to demonstrate the technology on off-road construction equipment. The target is to achieve improvements in fuel economy up to 70 percent, depending on the drive cycle.

Thursday, March 12

11:30 a.m. to 12:30 p.m.

Room S231

Efficient, Compact, and Smooth Variable Propulsion Motor

James Van de Ven, University of Minnesota

This work will develop a revolutionary variable displacement hydraulic motor for the propulsion drive of off-highway vehicles. The motor combines unmatched efficiency at all displacements, high displacement density, and low torque ripple. The high efficiency is a result of the mechanism using all rolling element bearings, low piston side-loads, and minimal unswept cylinder volume. The high displacement density is achieved through the radial piston packaging and a multi-lobe cam, creating multiple piston strokes per revolution. This talk will present the model driven design, optimization, and experimental testing of a prototype motor.

Friday, March 13

11:30 a.m. to 12:30 p.m.

Room S231

Hybrid Hydraulic-Electric Architecture for Mobile Machines

Perry Li, University of Minnesota

The project will develop a system architecture for off-road mobile machines that marries the benefits of hydraulic actuation and electric actuation to achieve both energy-saving and control performance. The proposed approach is especially useful for high power/high force machines that would be difficult to electrify directly with conventional Electro-Hydraulic Actuation (EHA) technologies. The project will also investigate how best to integrate electric and hydraulic machines to achieve efficient and power energy conversion devices.

AEM members interested in research and development projects of importance to the fluid power and off-road machine industries are welcome to attend.
