Embodiment Construction

[0013] refer to figure 1 , figure 2 , a high-g value accelerometer is composed of an acceleration-sensitive beam 1, two circuit boards 2, 3 and an SOI silicon micro-solid piezoresistive chip 4; the acceleration-sensitive beam 1 has symmetrical steps and positioning slots at its two ends , the two circuit boards 2 and 3 are symmetrically bonded on the steps, the SOI silicon micro-solid piezoresistive chip 4 is arranged in the middle of the acceleration sensitive beam 1, the SOI silicon micro-solid piezoresistive chip 4 and the two circuit boards 2 and 3 are connected through wires 5 connections.

[0014] The high-g value accelerometer is connected and fixed with the carrier (fuze assembly) by two fixing screws 6 through two positioning grooves on a plane, so as to realize the positioning of the accelerometer. During installation, the acceleration direction is perpendicular to the length direction of the acceleration sensitive beam 1 .

[0015] refer to image 3 , when the ...

Abstract

The invention discloses a high g acceleration value indicator. The indicator has a beam which is sensitive with acceleration, two circuit boards and a SOI silicon tiny solid pressed chip. On the beam, there is a symmetrical step with these two circuit boards. They are stick symmetrically on the step. The chip in the middle of the beam and it is linked with two boards by leads. The invention adopts the above-mentioned beam whose two ends are fixed steadily and the SOI silicon tiny solid pressed chip to compose a high g acceleration value sensor. It resolves problems about the high g acceleration value measurement in relation to the armour-piercing situation, the bunker invading, the drilling weapon and the aviation bomb directing system, etc. The invention owns characteristics such as high-distance measurement, dynamic research, strong endurance, high accuracy and heavy over loading.

Description

technical field [0001] The invention belongs to the field of production and application of acceleration sensors, and relates to a high-g value accelerometer based on SOI (Silicon-On-Insulator, silicon-on-insulator) technology. Background technique [0002] When armor-piercing, bunker penetration, ground-penetrating weapons attack targets, and aerial bombs are launched, the acceleration information generated is one of the main references for triggering the disarming of the fuze system and detonating the detonation system. With the development of new military ideas and the continuous progress of weapon technology, the test requirements for the acceleration of weapon systems are getting higher and higher, and the existing acceleration sensor devices can no longer meet the needs of modern warfare. For example, in the process of new missiles and rockets attacking targets, g×10 5 The above acceleration requires that the acceleration measurement device can ac...
