| Abstract: | 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. |
