Study on Parameters of MEMS Planar Zigzag Slot for Fuze

Abstract:

This paper has proposed a MEMS planar zigzag slot for fuze to discriminate between drop impact acceleration and smooth start acceleration. It can fulfill the requirements that fuze power should be activated reliably in smooth start environment and kept off in service handling environment. The planar zigzag slot is used in medium and large caliber ammunition. At first, a structure consists of a spring, a mass with an anchor, a fixed zigzag slot and two baffles has been proposed. Then, the working principle of the structure and motion of anchor after colliding to zigzag slot has been analyzed. At last, key parameters of the structure on the performance of acceleration recognition is studied by dynamic simulation.
