Abstract

This invention relates to a high overload three-degree-of-freedom accelerometer, which comprises a cubic base. The surface of base X, Y, Z direction is separately set with X axis, Y axis and Z axis acceleration beam separately covered with panels, wherein, acceleration beam comprises mass blocks connected to fixed end with beam and there is a SOI silicon solid state piezoresistive chip on the jiont of beam and fixed end. There is space between mass block and corresponding panel and base, which limits the motion range of mass block and protects high overload.

Description

technical field [0001] The invention relates to an accelerometer, in particular to an accelerometer with high overload and three degrees of freedom. Background technique [0002] When missiles, torpedoes, rockets and other weapons attack the target, the acceleration generated by the impact on the target is the main basis for determining that the fuze system of the warhead is disarmed and the detonation signal is given. With the development of missiles, torpedoes, and rocket weapon systems, the requirements for the acceleration test of the impact target are getting higher and higher, and new requirements are put forward for the applicability of the accelerometer test system. For example, when a missile, torpedo, or rocket hits a target, 10 5 The acceleration value of g, when the warhead fuze system hits the target to produce 200g acceleration, the acceleration measurement system is required to accurately measure the acceleration value, and provide the measurement signal to t...
