Problems solved by technology

[0003] With the further improvement of spacecraft model design requirements and test levels, the shock environment has become more and more severe, and the conventional vibration table or shock table can no longer meet its high-level explosion shock environment simulation requirements. A large-scale impact simulator is urgently needed

Embodiment Construction

[0024] The technical solution in the embodiment will be specifically, clearly and completely described below in conjunction with the drawings in the embodiment.

[0025] see Figure 1-2 As shown, a gas cannon-type vertical shock response spectrum testing machine includes an impact support seat 4, an impact plate 3, a base 7, a gas storage tank 9 and an impact tube 5, and the impact support seat 4 and the base 7 are fixed on the foundation. The impact plate 3 is fixed on the impact support seat 4, the gas storage tank 9 is fixed on the base 7, and its interior is filled with high-pressure gas, and is provided with a piston valve. The impact tube 5 is vertically located below the impact plate 3 and connected with The gas outlet of the gas storage tank 9 is connected through a connecting chamber 12, and a projectile 6 is arranged inside it. When the piston valve is opened, the projectile 6 obtains a certain speed under the promotion of high-pressure gas and impacts the impact pla...

Abstract

The invention discloses a gas gun type impact response spectrum testing machine. The testing machine comprises an impact supporting seat, an impact plate, a base, a gas storage tank and an impact tube, wherein the impact supporting seat and the base are fixedly arranged on a foundation, the impact plate is fixedly arranged on the impact supporting seat, the gas storage tank is fixedly arranged on the base and filled with high-pressure gas, a piston valve is arranged in the gas storage tank, the impact tube is vertically located below the impact plate and connected with the gas outlet of the gas storage tank through a connecting bin, a pellet is arranged in the impact tube, and when the piston valve is opened, the pellet has a certain speed to impact the impact plate upwards under the pushing force of the high-pressure gas. The testing machine can simulate high-magnitude impact rapidly and stably, the repeatability and uniformity of the tabletop of the testing machine and the speed control over the pallet are good, and the testing machine is convenient to install, maintain and use.

Description

technical field [0001] The invention relates to a shock environment simulation device, in particular to a gas cannon type vertical shock response spectrum testing machine, which belongs to the technical field of mechanical environment. Background technique [0002] The explosion shock experienced by the spacecraft mainly comes from a dynamic environment produced by various pyrotechnic devices on the spacecraft. A large number of pyrotechnic devices are usually used on spacecraft, and the explosive shock environment generated by these pyrotechnic devices can cause the spacecraft structure to produce a high-impact, wide-band, low-speed, short-duration transient response, and its acceleration amplitude can reach 3×10 ~3×10 g, the main frequency range is usually 1×10 ~1×10 Hz, and the duration generally does not exceed 20ms. During the impact process, the external energy is instantly transmitted to the spacecraft and its components, and the resulting sudden changes in d...
