摘　　要：动力总成悬置系统的性能参数设计的优劣直接影响到整车的NVH指标,这是整车开发的一项关键技术。以某国产客车为研究对象,在ADAMS中建立动力总成悬置系统的多体动力学仿真模型,并利用ISIGHT多目标优化法对悬置系统刚度进行优化设计。优化后的悬置能有效提高解耦率,从而改善系统的NVH性能。The stand of performance parameters of powertrain mount system design directly affects the vehicle＇s harshness （NVH） index,which is a key technology of vehicle development. In ADAMS soft, this dissertation builds up a multi-body dynamics model of Powertrain Mount System based on a domestic passenger car. And it carries out the optimization design of the system by using Multi-objective optimization in ISIGHT. Then the optimization results are analyzed, as a result, the effect of the former is better. The optimized suspension can effectively increase the decoupling rate, to improve the performance of harshness （NVH） on the system.
