摘要

MEMS (Micro-Electro-Mechanical System) acceleration switch is widely used in automobile, aviation and military project. The contact stability is one of the important factors to evaluate the acceleration switch. The latching acceleration switch is composed of the mass-spring system and the latching mechanism. This paper researches the contact face on the symmetrical Lshape latching mechanisms by theoretical analysis and simulation, and researches the stability of the symmetrical L-shape latching mechanisms in comparison with the barb latching mechanism. The research of the contact surface shows that the arc curved contact surface shape is easier to be latched in symmetrical L-shape mechanisms. Combined with the symmetrical Lshape latching mechanisms and the barb latching mechanism, the result shows that the symmetrical Lshape latching mechanisms are easier to be latched than the barb latching mechanism with t he same latching size. With the study of this paper, a theory reference for the study of the latching acceleration switch will be laid.
