Abstract

A novel semi-active vibration control technique using magneto-rheological (MR) damper is presented in this paper for researching the key points that help realize the control of semi-active seat suspension. Bingham model is applied to establish for MR damper in this method, and the dynamics simulation on vehicle seat semi-active suspension system is carried out. In the case of random input of the Grade B road, the vibration characteristics of vehicle seat are analyzed and the effect of spring stiffness, damping, and vehicle speed on the vibration damping characteristic is discussed as well. Simulation results show that the semi-active suspension has a higher damping performance than passive suspension. PID control strategy is introduced to the semi-active suspension; the maximum acceleration decreases obviously to around 40 % compared with passive suspension that confirms that the effect of control strategy has played well.
