| 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. |
