Magneto-Rheological Fluid Semiactive Suspension System Performance Testing on a Stryker Vehicle

Abstract

A Magneto-Rheological (MR) Fluid Semiactive Suspension System was tested on a Stryker vehicle, Infantry Carrier Variant (ICV), to determine the performance improvements compared to a standard ICV Stryker vehicle. In January 2005, the testing was conducted at the U.S. Army Yuma Proving Grounds located in Yuma, Arizona. The testing was conducted under the guidance of the U.S. Army Tank-Automotive Research, Development, and Engineering Center (TARDEC) of Warren, Michigan and MillenWorks of Tustin, California. The core of the system tested is comprised of 8 dampers and controllers using proprietary algorithms to modulate individual wheel forces in response to terrain inputs and body motion. Functionality of the Standard Stryker vehicle's pressurized gas spring and ride height management system was fully retained while maintaining the physical envelope of the original damper. The system's low power consumption (80 watts idle, estimated 250 watts cross-country, and 800 watts theoretical peak) did not require an additional power source. The MR Suspension system was intentionally designed to maintain the standard wheel travel, spring rate, and spring gas volume.
