摘　　要：汽车动力总成悬置系统是汽车振动系统的一个重要子系统,对改善汽车平顺性和降低汽车噪声有很大影响,合理的汽车动力总成悬置系统的设计可以明显降低汽车动力总成和车体的振动。本文针对某混合动力公交在怠速工况下车厢地面振动偏大的问题,对原悬置系统进行测试和减振性能分析,并对测试方法和实际测试效果进行了说明。The vibration and noise performance have been the important standard to measure whether the vehicle is good ornot.The mount system of automobile power is one important system of the vibrating system.It has much influence inimproving automobile smoothness and decrease noise.Proper design of automotive powertrain would greatly reduce thevibration of automotive powertrain and body.This paper aiming at the vibration problem of a hybrid electric bus underengine idling condition,a text and a vibration-attenuation characteristic analysis of the original mounting system arecarried out,I elaborated the test and actual text results.
