Abstract

This paper describes the stability research of MEMS spring used in fuze. The micro-spring in thickness dimension is thin, while the size of axial direction is larger, during compression the micro-spring is prone to suffering buckling and become unstable. In order to consider the extreme environments in launch, this paper aims to carry out buckling simulation in high or low temperature, by using FEM analysis. The effect of temperature load on the micro-spring buckling can be obtained. These researches can provide theory reference for the design applications and reliability analysis of micro-spring, and also lay the foundation for the response characteristics of the micro-scale elastic components under compressive force.
