摘　　要：针对某重型汽车在怠速工况下抖动严重的现象,利用ADAMS建模分析,发现悬置系统固有频率太高且解耦率差。因此,利用ADAMS的优化功能,确定出悬置系统的改进设计参数。试验表明,改进后的悬置系统有效地解决了车辆抖动的问题。Specific to the serious chattering phenomenon of a heavy duty vehicle under idling condition, using ADAMS modeling analysis, it＇s discovered that the mounting system＇s natural frequency is too high, and the decoupling rate is poor. Thus, by using ADAMS＇s optimization function, the improved design parameters of the mounting system can be determined. Experiment shows that the improved mounting system solves the chattering problem effectively.
