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.

Phase II Amount
$505,667
In this Phase 2 SBIR, we will build 3 sets of regenerative, semi-active shock absorbers, install them on a test HMMWV, and demonstrate damping, energy regeneration, and durability in a field test. The Company will advance semi-active control algorithms, and prepare the combination of mechanical components and electronics to fulfill GenShock’s capabilities. Subsequently, Stryker-GenShock units will be modeled and simulated, designed, fabricated, and tested to demonstrate the ability for GenShock technology to scale to additional platforms. Advanced semi-active control algorithms will be prepared for Stryker to provide rudimentary and advanced control, depending on the application.
