Abstract 1

Progress on the development of active suspension for improving mobility of rough terrain vehicles is being hindered by the potentially high energy requirements. A unique regenerative active suspension system has been conceived and is being developed to provide active suspension with very low energy requirements. Regenerative active suspension consists of multiple variable displacement pumps, each controlling flow to and from hydro-pneumatic struts to control a vehicle's low frequency body motions. When fluid is returned from a strut to a pump, energy is recovered or “regenerated” so that the total energy requirement is very low. This paper presents the results of a study showing the potential of the regenerative active suspension system to improve vehicle control and ride comfort of rough terrain vehicles enhancing mobility while requiring very little additional energy. Simulation results are presented for both tracked and wheeled vehicles, comparing regenerative active suspension to passive suspension and other forms of active suspension. The design of a compact, efficient, multiple pump unit will also be presented which makes it possible to incorporate this system in rough terrain vehicles. Results of pump simulation and pump testing will be presented.

Abstract 2

This project will demonstrate the feasibility of using regenerative suspension technology with semi-active control capabilities to both harness waste energy from military vehicle suspensions and simultaneously improve ride quality/handling. The proposed effort includes modeling, simulation, and evaluation of a power regenerative suspension system based on empirical and modeled results from GenShock, our breakthrough regenerative suspension technology. GenShock harvests waste energy on vehicles, machines, and aircraft, turning linear motion into usable electric power. GenShock extends vehicle range, improves maneuverability, augments fuel economy, and increases the readiness and survivability of the force. Simultaneously and without sacrificing power generation, GenShock improves stability, safety, maximum all-terrain speed, and ride quality of ground vehicles and weapons platforms. In semi-active mode, GenShock stiffens and softens the suspension in concert with terrain and other parameters. The proposed system utilizes proven hydraulics and electromechanical technologies in a durable and low-cost packaging for optimal performance, durability, and cost/benefit.
