摘要

基于弹道修正引信发射时的轴向高过载条件以及引信中隔转平台的缓冲结构特点,建立了缓冲动力学模型;利用Ansys/LS-DYNA对弹道修正引信隔转平台进行动力学仿真分析,根据隔转平台中易故障部件的应力分布评估其缓冲保护特性;并设立了多个仿真组,对比分析了不同缓冲结构、缓冲材料以及材料参数对隔转平台缓冲保护性能的影响;根据仿真结果得出采用多垫缓冲结构的隔转平台缓冲保护特性更好,同时通过优化缓冲垫的材料以及材料参数进一步提高了隔转平台的缓冲保护能力。

Abstract

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.
