Based on the axial high overload condition for trajectory correction fuze and the buffer structure of the bypass platform, the buffer dynamic model is established. The dynamic simulation analysis of the trajectory correction fuze platform is carried out by ANSYS/LS-DYNA. The cushioning characteristics are evaluated according to the stress distribution of the faulty parts in the platform. The influence of different buffer structures, cushioning materials and material parameters on the buffer protection performance of the platform is compared and analyzed. According to the simulation results, it is concluded that the buffer protection effect of the multi-cushion buffer structure is better, and the buffer protection capability of the platform is further improved by optimizing the material and material parameters of the cushion.
