摘　　要：面对弹道修正引信中光学组件无法承受弹丸高发射过载的迫切需求,针对某型制导炮弹成像引信光学系统,结合仿生理念提出一种引信光学系统减振方案。将竹子的宏微观结构应用于金属薄壁管,为光学系统设计两种具有竹子结构特征的金属薄壁套筒,并同时设计由橡胶垫与碟簧复合的减振装置。利用有限元分析软件进行动力学仿真验证设计结构模型的减振效能。仿真结果表明:所提减振方案能够缓解光学系统受到的冲击并降低变形值,两种透镜外筒应变峰值降低40%、72%,光学传感器应变峰值降低68.21%、52.49%,证明该减振方案具有良好的减振效果。所提方案为光学部件在高过载引信中的应用提供新思路。The optical components in the trajectory correction fuze can not be subjected to the high launch overload of a projectile.A shock absorption method for the optical system of the fuze is proposed based on the bionic concept.The macro-and micro-structures of bamboo are applied to a metal thin-walled tube,and two kinds of metal thin-walled sleeves with the characteristics of bamboo structure are designed for the optical system.And also a shock absorption device composed of rubber pad and disc spring is designed.The finite element analysis software is used to carry out dynamics simulation to verify the shock absorption efficiency of the designed structure model.The simulated results show that the proposed shock absorption method can be used to alleviate the impact on the optical system and reduce the deformation value.The peak strains of two lens outer cylinders are reduced by 40%and 72%,respectively,and the peak strain of the optical sensor is reduced by 68.21%and 52.49%.It is proved that the proposed shock absorption method has a good shock absorption effect.This strategy provides a new idea for the application of optical components in high overload fuze.
