IFPE Research Symposium

IFPE Research Symposium

Hosted by the National Fluid Power Association

When mapping out your IFPE schedule, be sure to keep the lunch hours on March 11, 12, and 13 open for the IFPE Research Symposium. Over these three days, the National Fluid Power Association will be presenting 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.

Attendees can register to attend one or more of the sessions. Our three distinguished presenters are:

Wednesday, March 11
11:30 AM to 12:30 PM
Room S231

Individual Electro-Hydraulic Actuators for Off Road Machines
Andrea Vacca, Purdue University

This project proposes a new technology for electro-hydraulic actuators suitable for off-road construction machines. The main project goal is accomplished by formulating a novel design for a four quadrant electro-hydraulic supply unit, which is coupled to a linear actuator by means of a hydraulic circuit that minimizes the throttling loss. The project takes as reference the case of a compact wheel loader, for which it is expected to achieve an improvement on the energy consumption of the hydraulic system up to 70%, depending on the drive cycle.

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 AM to 12:30 PM
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 that 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.

 

Anyone interested in research and development projects of importance to the fluid power industry is welcome to attend, with pre-registration required to reserve one of the complimentary lunches each day.
