Parametric design of MEMS fuze safety release insurance mechanism

At present, MEMS safety systems have the disadvantages of complex structure and easy to be affected by the electromagnetic environment of the battlefield. Based on this, this paper proposes a planar structure to realize remote protection of MEMS security systems. First, a theoretical analysis of the MEMS remote release insurance mechanism is carried out. It mainly calculates the centrifugal force of the centrifugal slider, the magnitude of the deflection of the threshold elastic beam caused by the active tooth collision fixed tooth, and the time when the active tooth of the safety mechanism is released by the fixed tooth. Then, the motion characteristics of the mechanical MEMS remote release insurance mechanism are analyzed by simulation. Through theoretical analysis and simulation analysis, the theoretical calculation results of the maximum deformation of the active tooth are in good agreement with the simulation results, and the error is less than 9.7%. The delay time can reach 1.33ms or more, which meets the requirements.
