Performance Analysis of a Novel MEMS Terminational Latch Mechanism
A novel latch mechanism of centrifugal system in the MEMS fuze S&A mechanism was mechanically analyzed by FEA. By the analysis, the equation of resistance was determined, the same as the equation about the angular velocity of centrifugal system and the reliability of the slider inserting, which were validated by FEA. Setting different parameters in the analysis and comparing the speed curves of sliders inserting into the latches, one method was determined to reduce the vibrating of speed curve. According to the characteristic of MEMS fabrication technology and design requirement for latch mechanism, one of higher reliability and smaller amplitude oscillation of speed curve was selected to simulate when it was imposed by reverse force.
