摘　　要：某自卸车在怠速工况下驾驶室抖动异常,驾驶室舒适性很不理想,为找出其原因进行了原地驻车试验,通过分析比较不同转速下悬置系统隔振前后的能量传递与频率分布,得出的结论为悬置系统与动力总成以及车架的匹配不合理,对振动的衰减起了反作用,左侧前悬置为隔振效果较差的部位。采用多体动力学方法建立动力总成悬置系统动力学模型,对动力总成悬置系统的刚度进行优化,使悬置系统与动力总成及车架的匹配更加合理。The dump truck has abnormal vibrations when it is working on the idling speed. To find the reason to optimizing the mounting system, the experiments that the truck stays where it is are proceeded by the different speeds of the engine. The energy transmission and the fiequency distribution are analyzed and the reason of the abnormal vibrations is that the matching of the mounting system is＇ not very well. The performance of the left side of the front motinting is the worst. By multi-body dynamics method, the kinetic model of the powertrain mounting system is established. The matching of the mounting system is better through the optimization in the model.
