| Abstract: | The dynamic finite element method is applied to establish a finite element model for a certain vehicle. According to national standards of the vehicle impact test, numerical simulation and experiment test of the vehicle are conducted. The comparison between numerical simulation and experiment test shows that the deformation of the vehicle calculated by numerical simulation complies well with that of the experiment test. The acceleration curves on some primary parts are also similar in shape. This result indicates that it is practicable to carry out numerical simulation of vehicles by finite element method. The analytical results provide some referential criteria for the safety design of vehicles. |
