Abstract
Aiming at the problem that the structure of the recoil safety mechanism in the existing MEMS security system is too complicated and the processing is inconvenient and the stress of the test piece engineering process is too complicated, a micro-inertial pin recoil security mechanism which can be used for the MEMS security system was proposed.The feasibility of the micro-inertial pin recoil security mechanism was verified by a combination of theoretical analysis and finite element analysis.The simulation results show that the micro-inertial pin recoil security mechanism can distinguish between service drop and normal launch environment.By tilting the micro-inertial pin, the displacement of the inertia pin can be reduced, and the MEMS security system is more compact in axial direction, which meets the requirements of the MEMS safety system for the axial small size of the flameproof actuator.Compared with the slider type and cantilever type recoil security mechanism, the micro-inertial pin rear seat security mechanism significantly reduces the structural complexity and improves the processing performance of the mechanism.关键词
