Abstract：Abstract: Magnetorheological Damper is an ideal semi-active control device for vehicle suspension. The behavior of magnetorheological dampers is important for control algorithm. Based on Bingham，bi-linear and bi-linear hysteresis models, a new dynamic model with an arctangent function was presented, it was the extension of the former three models and could describe force-velocity behavior more close to the experimental data, the parameters of the model had definite physical meanings. An experiment was conducted to verify the precision of the new model.
