N2 - With the intelligent development of small-caliber ammunition, the overall size of the fuze is compressed. In this paper, a theoretical method-energy statistical method has been proposed according to the MEMS S&A device. Taking the slider mass, micro-spring stiffness, latch mechanism size, and initial offset distance into account, the conversion relationship among each part of energy in the process is obtained. For an existing structure of MEMS S&A device, known parameters are utilized to reverse the overload value at arming condition. The ANSYS/LS-DYNA finite element analysis software is used for simulation analysis, thereby confirming the feasibility of theoretical calculations. Also, theoretical calculation error ε is obtained, which to be 0.7%. Energy statistical method and simulation analysis serve as theoretical references for the design of the MEMS S&A device.
