Abstract

A V-shaped-structure MEMS (micro-electromechanical system) actuator for a detonating sequence comprises a monocrystalline silicon substrate and anchor points. A monocrystalline silicon structure layer is bonded with the monocrystalline silicon substrate with a silicon dioxide insulating layer grown thereon, a metal electrode layer is deposited on the monocrystalline silicon structure layer, the MEMS actuator is manufactured in the monocrystalline silicon structure layer, two ends of a V-shaped beam thermoelectric driving unit of an array structure are connected with the anchor points, a middle arm is positioned in the middle of and mutually fixed with the V-shaped beam thermoelectric driving unit, two ends of a flexible beam are connected with the middle arm and the head end of a lever, and a partition is processed at the tail end of the lever to cover an acceleration bored hole. Thermoelectric effect and thermal expansion effect of silicon materials are utilized, and the V-shaped-structure MEMS actuator for detonating the sequence has the advantages of low cost, high intelligence and easiness in integration.

Description

technical field [0001] The invention relates to the technical field of fuzes, in particular to a V-shaped structure MEMS actuator for detonation sequences. Background technique [0002] The fuze is a control device (system) that uses target and environmental information to detonate or ignite the charge of the ammunition warhead under predetermined conditions. It is usually installed on rockets, missile warheads, and gun / tank / mortar ammunition, etc., according to the type of ammunition Different fuzes are selected according to different targets and the needs of dealing with targets. The fuze is an important part of the weapon system. It detects the environment and targets to obtain information, process and identify information, and realizes the safety state control and optimal detonation control of the fuze. The basic functions of the fuze are "safety" and "reliable detonation of the warhead". The safety device in the fuze is an important part of the fuze system. One of its...
