| 摘 要： | 为研究汽车制动过程中鼓式制动器的低频振动,在系统五自由度非线性动力学模型基础上,对系统的稳定性进行了分析。分析发现:即使仅考虑恒定的摩擦系数,系统也会随着内部某些结构参数的变化从稳定状态变成不稳定状态。

| Abstract: | To study the low-frequency vibration of drum brake of the automobile in the course of braking,a non-linear equation of 5-degree of freedom is established.By the analysis of stability of the system,it concludes that the vibration and instability can occur with the variation of some specific parameters,even if the friction coefficient is constant. |
