摘 要:
对某轿车白车身进行了计算模态分析，得到其计算模态频率以及相应的振型，并通过试验得到试验模态频率及振型，根据振型相关性理论，对试验和计算模态及振型进行相关性分析，将有限元的动态分析与试验数据有机地结合起来，验证了白车身有限元模型。[著者文摘]

Abstract:
The calculated modal of a given car BIW （body-inwhite） was analyzed and its modal frequency and the corresponding shape were obtained from this calculation. Based on the shape correlation theory, a correlative analysis of the modal frequency and shape both from the calculation and the experiments was carried out. The result from the correlative analysis proved that the dynamic analysis by the finite element model of the BIW was available for practice use.[著者文摘]
Key words:
