摘要
对某车辆车身进行了计算模态分析 ,得到其计算振频以及相应的振型 ,并通过试验得到试验模态频率及振型 ,对计算模态和试验模态进行振型相关性分析 ,将有限元的动态分析与试验数据有机地结合起来 ,验证了车身有限元模型 ,为车身结构设计提供了依据。
The calculated mode of a given car-body was analyzed and its oscillating frequency and the corresponding mode were obtained from the calculation. A correlative analysis of the oscillating frequencies and modes both from the calculation and the experiments was carried out. The results from the correlative analysis proved that the dynamic analyses by the finite element model of a car-body was available for practice use.
