High impact acceleration test system and test method

Abstract

The invention provides a high impact acceleration test system and test method. Through collision of a test projectile and an incident bar of a Hopkinson bar, an impact acceleration signal having an amplitude of (1-8)*104g and a pulse width of 0.5ms to 2ms is generated, and a test system and a test method are provided for researching various performances of a missile-borne electronic device in a high compact environment. The high impact acceleration test system and test method are high in impact energy and controllable in an impact environment and have good repeatability and leading technical performance. The test method can provide an impact environment having an order of magnitude similar to that of a large real test for a subsystem and a component product of a kilogram scale in laboratory conditions, can be applied to study the impact resistance of a penetrating fuse and the buffer performance of a buffer material, calibrate an acceleration storage test device, study the zeroing characteristic of a high impact accelerometer and so on, and can also provide test conditions for studying the impact resistance of other missile-borne electronic device, such as a micro-electro-mechanical system (MEMS) device, a black box, a spinning top, a chip and so on.

Description

technical field [0001] The invention belongs to the technical field of impact testing and testing, and in particular relates to a high impact acceleration testing system and testing method. Background technique [0002] Advanced offensive weapons represented by penetrating or ground-penetrating projectiles sense target information, control detonation time and position, so as to maximize the weapon's destructive power. During the penetration process, the electronic equipment on the bomb usually needs to experience a duration of several milliseconds and an amplitude of tens of thousands of g (1g=9.8m / s 2 , the same below), whether it can withstand the test of the high-impact environment is related to the completion of the entire combat mission. In order to improve the reliability of the electronic equipment on the missile and reduce the risk in actual combat, in the process of its development and production, it is necessary to carry out targeted impact resistance tests to as...

Problems solved by technology

Live ammunition shooting can provide a more realistic impact environment. The main technical means include artillery test, balanced gun test, rocket sled test, airdrop test, etc., but these methods have disadvantages such as high test cost, long test cycle, poor repeatability, and small number of samples. Not suitable for extensive research experiments
