摘要
介绍了汽车关键点动态特性重要性,建立了评价动态特性的速度频率响应函数,利用Point Mobility方法对算例进行了模拟计算,分析结果显示该方法能有效的预测动态特性存在的问题,为结构修改提供重要的依据。
It introduces the importance of the dynamic stiffness to critical point,and educe the frequency response function evaluating the dynamic characteristic. An example is simulated with mean of Point Mobility. The results show that this mean can effectively forecast the problem to the dynamic characteristic,and can provide the vital evidence for structure modification.
