Paper Abstract

This paper proposes applies MR fluid based suspension system to military vehicle for vibration control. The suspension system consists of gas spring and MR damper. In order to model of MR damper, a quasi-static modeling of the damper is conducted on the basis of Bingham model of MR fluid after describing the configuration and operating principle of the MR damper. And then the lumped parameter models of MR fluid flows in the damper are established and integrated to whole damper system by taking into account for dynamic motions of annular duct and gas chamber. Subsequently, a military vehicle of 6WD is adopted for the integration of the MR suspension system and its nonlinear dynamic model is established by considering vertical, pitch and roll motion. Then, a sky-hook controller associated with semi-active actuating condition is designed to reduce the imposed vibration. In order to demonstrate the effectiveness of the MR suspension system, computer simulation is undertaken showing vibration control performance such as roll angle and pitch angle. This is vibration control evaluated under bump and random road profiles.
