摘要
以轿车后悬挂系统作为研究对象 ,将汽车简化成两个自由度的振动系统 ,采用改进的非高斯闭合法计算车辆在路面谱激励下车身振动加速度均方根值、车轮与路面间相对动载及悬架的穿越频率 .在此基础上提出了一种对汽车悬架非线性阻尼进行优化设计的方法 ,该方法在汽车动态设计研究中具有一定的实用价值 .
In this paper,a dynamic model with two degree of freedom was established for automobiles. In this model,the methed of non Gauss closure is used to calcalate root mean square of acceleration for auto body, dynamic road between wheel and ground, and passing through frequency of suspension, under the road spectrum random excitation.The results show that this method can be better used in the optimal design of damping for the automobile suspending system.
