To solve the structural strength problem of a MEMS arming device for a fuze, a kind of arming device applied to a certain type of 40 mm grenade is designed. This paper introduces the working principle of the arming device; simulates the shear pin, rotary pin and locking mechanism in the device; designs a variety of different test tools for test verification; and further increases the explosion reliability and arming safety tests. The results show that the arming device improves the structural strength and can meet the action requirements of a certain type of 40 mm grenade for safety release, as well as the application requirements of explosion reliability and arming safety.
