| Abstract: | The front crash of the front rail for Chang＇an minicar was simulated by HyperMesh and LS-DYNA software. The front rail structure was optimized and the capability of absorbing energy of the front rail before and after improvement was compared. The simulation results show that the crashworthiness of the improved front rail is enhanced. It provides certain references for further improving the crashworthiness of the ear. |
