Based on researching the multiring structure of Magnetorheological MR damper developed independently by Civil Aviation University of China and the fundamental performance parameter of MR fluid MRF,the damping force of the calculating formula was formulated by using the experiments. A multi- body dynamic model of the 1-4 vehicles’ suspension was built by using virtual prototype model. and the fuzzy control system for the semi-active suspension was designed under the MATLAB-SIMULINK environment. The co-simulation of ADAMS and MATLAB were carried out. The results of simulation shows that the semi-active suspension made up of the virtual prototype model and fuzzy control strategy can reduce the vehicle’s vibration and improve the ride comfort characteristics. The Co-simulation method also offers a new way to the simulation of complex dynamic system and control strategy.
