| Abstract: | Great improvements have been made on the design of a certain newly remolded fuel cell vehicle on the basis of its original pattern ; an all new design has been carried out on its subframe. Utilizing finite element analytical software Hyperworks, the finite element modeling of the subframe was carried out, the structural strength of subframe was analyzed and the modality of subframe was calculated. The strengthened vibration test verified the result of finite element analysis and reflected the probably existed problems of the entire vehicle. It provided a strong foundation for further improvement on the structure in essence of theory and practice. |
