摘　　要：针对现有MEMS引信后坐保险机构较为复杂,要求加工精度高等特点,提出一种MEMS后坐悬臂梁保险机构,利用有限元软件对该保险机构进行的动力学仿真表明:新的后坐保险机构以一对悬臂梁及其框架代替了其他机构中的带曲折齿的后座滑块、后坐弹簧、闭锁机构等模块,结构简单、加工精度要求低。For the existing MEMS setback safe and arming systems（SA） has complicated structure and need high precision processing,a new MEMS SA with a new style cantilever setback arming device was put forward.In this device,a pair of cantilevers and it＇s frame took place of setback slide with zigzag teeth,setback spring,and locking mechanism in the former designs.The dynamic simulation with ansys module of the setback arming device showed that the new design of the MEMS setback device was of simple structure and low machining precision.
