摘　　要：在ADAMS/VIEW中建立某轿车前麦弗逊悬架动力学模型,在MATLAB/SIMULINK中建立C级路面激励,并将此路面激励导入到ADAMS中作为悬架测试平台的驱动,然后将悬架动力学模型导入到MATLAB中,并在MATLAB中建立开关式天棚阻尼半主动控制策略,进行联合仿真。仿真结果表明,悬架通过半主动控制,可以有效的降低车身加速度和悬架动挠度,提高了平顺性和乘坐舒适性。First, a car front macpherson suspension dynamic model is set up in ADAMS/VIEW, and the C level road excitation is built in the MATLAB. Then, import the road excitation into ADAMS as the motion of suspension test platform .Then the suspension is imported to the MATLAB, and the Skyhook damping semi-active control strategy is established in the MATLAB, and then starting the co-simulation. The simulation results show by the effect of semi-active control the suspension can not only effectively reduce the body acceleration and the suspension dynamic deflection but also improve the ride comfort.
