| Abstract: | This paper made the parameterization modeling for a certain entire-bearing coach body frame, and carried out the static response analysis. Then the static and dynamic experiments of the coach body were conducted. The results of the experiments have testified the analysis done above,and based on the former modal analysis results, the sensitivity analysis was performed,and the important parameters were obtained to optimize, and propose the structure lightweight plan. According to the plan, the body frame reduces 273. 4kg altogether. Through the CAE analysis as well as the static and dynamic experiments , the improved coach body indicates that after lightweight the body' s rigidity and stress satisfied the requests. |
