Pneumatic device for pneumatic type horizontal impact table

Abstract

The invention relates to a pneumatic device for a pneumatic type horizontal impact table. The pneumatic device for the pneumatic type horizontal impact table comprises an impact push plate, an impact air cylinder, an air cylinder support and an air storage cylinder, wherein the impact push plate is fixedly arranged on a piston rod in the impact air cylinder, the impact air cylinder is connected with the air storage cylinder, and the impact air cylinder and the air storage cylinder are fixedly arranged on an impact table base through the air cylinder support. The energy of the pneumatic device for the pneumatic type horizontal impact table is much larger than that of pendulum bob impact on the aspect of achieving the maximum impact energy of impact hammers, and thus the demands of high-order impact response spectrum simulation test verification of spacecraft products can be met.

Description

technical field [0001] The invention belongs to the field of spacecraft dynamics test, in particular to a pneumatic device of a pneumatic horizontal impact platform. Background technique [0002] During the full mission of the spacecraft, it needs to experience various types of mechanical environments, including vibration, noise, shock, acceleration, etc. Among them, the impact environment is mainly generated by various pyrotechnic devices on the spacecraft during the working process. The explosion impact environment is one of the most intense dynamic environments experienced by the spacecraft. It should be completed by means of explosive shock environment simulation test to improve the reliability of the product. After the release of GJB1027A, the shock response spectrum test is used to simulate the explosion impact, and the shock response spectrum test requires higher equipment capabilities. At present, it is mainly realized in two ways. One is to calculate the correspon...

Problems solved by technology

The disadvantages of this method are: the uniformity of the table is not good, the inflection point of the shock response spectrum is higher than 2000Hz, and the shock test of only a few kilograms of products can be completed

[0005] At present, the impact test level of spacecraft products is generally required to exceed 1000g, and the impact test level of some products has reached 2000g, and even the impact test level of some models exceeds 3000g. 200kg, the current technical conditions of the test cannot meet the needs of the test

In order to meet the needs of the increasing development of spacecraft, avoid insufficient assessment of spacecraft products during the test process, and fail to fully expose product design and manufacturing defects, it is urgent to develop a system that can perform high-level impact tests based on aerodynamics for spacecraft subsystems. , the development of a high-level pneumatic level impact test system must first solve the problem of providing the pneumatic device required for the impact test. The pneumatic device needs to meet the energy required for the test and is safe and reliable.
