摘　　要：介绍了汽车单质量系统的频率响应特性;研究了阻尼变化对汽车不同减振频域的振动响应;计算了刚度变化对汽车振动阻尼的影响,进一步分析了由振幅或压缩行程不同形成的4级刚度悬架对汽车振动特性的影响。The character of frequency response of a single-mass vibrating system is introduced. Vibrating response due to the changing of dampening in different vibrating frequency domain is studied. Dampening changes due to the rigid changes was calculated, and furthermore, the results of the damping vibration of fourth-rigid suspension automobile due to the vibrating amplitude or the compression travel are analyzed.
