Problems solved by technology

[0004] At present, the shock environment provided by equipment such as electrodynamic vibration tables and pendulum impact tables generally ranges from 10Hz to 5000Hz, and the maximum response level is only 5000g, which cannot simulate a higher level shock environment, so it cannot be truly assessed Shock Resistance of Spacecraft Products

Abstract

The invention discloses a pressure control system used for a gas gun bounce table. The pressure control system comprises one cylinder group (1), wherein the cylinder group (2) is communicated with a first manual switching valve (31); the first manual switching valve (31) is respectively communicated with a first air inflation branch circuit (100) and a second air inflation branch circuit (200); the first air inflation branch circuit (100) is communicated with an inner air chamber (7) in the gas gun bounce table and used for carrying out air inflation on the inner air chamber (7); and the second air inflation branch circuit (200) is communicated with the an outer air chamber (8) in the gas gun bounce table and used for carrying out the air inflation on the outer air chamber (8). The pressure control system disclosed by the invention can safely and reliably control the gas gun bounce table to launch pills outward, and a high-speed impact resonant plate produces a high-order shock response spectrum, so that an explosion separation shock environment produced by a pyrotechnic device on a spacecraft product during action is simulated.

Description

technical field [0001] The invention relates to the technical field of mechanical environment tests, in particular to a pressure control system for an air cannon impact table. Background technique [0002] Various pyrotechnic devices on aircraft in the aerospace, aviation, ordnance industries will produce explosive separation and impact the environment when they operate, resulting in a high-level, wide-band, and short-duration transient response of the aircraft structure. [0003] The main frequency range of the explosion separation shock is in the range of 100 Hz to 100000 Hz, the response amplitude of the aircraft structure is in the range of 300 g to 300000 g, and the duration generally does not exceed 20 ms. During the impact process, the instantaneous energy transfer may cause the mechanism failure of the aircraft, resulting in the failure of the spacecraft to work normally, seriously affecting the service life and safety performance of the spacecraft. Therefore, how t...
