Abstract: In this paper, a semi-active control of vehicle suspension system with magnetorheological (MR) damper is presented. At first a MR damper working in flow mode is designed. Performance testing is done for this damper with INSTRON machine. Then a mathematical model, Bouc-Wen model, is adopted to characterize the performance of the MR damper. With optimization method in MATLAB and experimental results of MR damper, the coefficients of the model are determined. Finally, a scaled quarter car model is set up including the model of the MR damper and a semi-active control strategy is adopted to control the vibration of suspension system. Simulation results show that with the semi-active control the vibration of suspension system is well controlled.

Keywords: magnetorheological (MR) damper ,modeling, testing ,parameters estimation, simulation,simulink.
