| Abstract: | As to the passive safety of high speed train, based on large deformation collision theory, the collision is simulated by PAM CRASH, the topology optimization is performed on train body end anti collision devices, and then the lightweight design is implemented on the devices. The results show that the stability of the anti collision device structure is ensured while the maximum impact force is reduced by 23% and the mass is reduced by 33.6%. The purpose of improving the passive safety of train is achieved. |
