Problems solved by technology

In the penetrating test of the projectile hard target, the electronic device on the projectile will bear the impact acceleration of tens of thousands or even hundreds of thousands of g. This shock acceleration may lead to the failure of the electronic device on the projectile, causing irreparable losses

Abstract

In the invention, a high g value impact acceleration simulation test system, a method thereof and the application of the test method, belonging to the technical fields of impact testing and tests. The test system comprises three parts: the high g value impact acceleration simulation test system, the test method and the application of the test method. In the high g value impact acceleration simulation test system and the test method, an impact acceleration signal with the amplitude of (0.1-1.5)*10<5>g and impulse width of 150-600mus is generated by the collision of a projectile shot by a gas cannon and a collided object, thus providing the test system and the test method for various performance researches on a projectile-borne electronic instrument under high impact environment. The test system and the test method have advanced designs and leading technical performances, can be applied to the aspects of projectile-borne testing instrument, inertial measurement unit, black box, intelligent fuze, gyro, MEMS device and the like for the calibration of an acceleration storage testing device under application environment, high impact resisting performance research of the projectile-borne electronic instrument, cushion performance research of a cushion part of a projectile-borne testing device and return-to-zero characteristic research of a high impact accelerometer.
