specific Embodiment approach 1

[0027] Specific implementation mode one, see figure 1 In the shown light gas cannon launching device, the high-pressure gas chamber 1 of the large-caliber light gas cannon is connected with the upper port 6-1 of the coupling connector 6 through a flange and a sealing O-ring; The left end face position of the light gas cannon launch tube 2 has an annular hole 6-3 through which the high-pressure gas chamber 1, the coupling connector 6 and the large-caliber light gas cannon launch tube 2 inner cavity are communicated with each other, Ensure that the gas pressure of the high-pressure chamber 1 before and after the test is the same as the gas pressure at the small end of the aluminum alloy piston 5; install a pressure gauge or a pressure sensor 13 on the high-pressure chamber 1 to monitor the pressure of the chamber; a large-caliber light gas gun The high-pressure gas chamber 1 is connected with the high-pressure gas storage tank 8 through the pipeline, the four-way and the solenoi...

specific Embodiment approach 2

[0035] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the flying plate 3 is replaced by a foam (such as aluminum alloy foam) projectile, and the target structure to be studied is used for the underwater explosion equivalent loading simulator. By replacing it, the laboratory simulation test research on the structural damage characteristics of the explosion shock wave load in the air and the high-speed fragment coupling effect can be realized.

Abstract

The invention provides a light gas gun launcher for simulating explosive shock wave and high speed fragment coupling load, and belongs to the technical field of light gas gun simulation. According tothe light gas gun launcher, the problems that a live ammunition explosion loading mode is high in qualification requirements for experiment and can not be popularized, while the effectiveness of the live ammunition explosion loading mode can not be determined by fully utilizing a numerical simulation technology are solved. According to the scheme, a small caliber light gas gun launching tube is coaxially arranged in a large caliber light gas gun launching tube through a coupling connector, and a sabot flying plate is arranged in a front end inner cavity between the two tubes; the rear end of the small caliber light gas gun launching tube extends out of a rear port of the coupling connector, and communicates with a small caliber light gas gun high pressure air chamber; an upper port of thecoupling connector communicates with a large caliber light gas gun high pressure air chamber, and a piston is arranged between the large caliber light gas gun launching tube and the rear end of the coupling connector, slid right and left along the inner wall of the coupling connector, and used for opening or closing a channel between the large caliber light gas gun high pressure air chamber and the large caliber light gas gun launching tube; and a high pressure gas storage tank is used for providing a high pressure gas source.

Description

technical field [0001] The invention belongs to the technical field of simulated light gas cannon, and relates to a non-drug (high-pressure gas-driven) light gas cannon launcher for simulating underwater and air explosion shock waves coupled with high-speed fragment coupling loading to carry out systematic experimental research on the damage characteristics and mechanism of structural materials device. Background technique [0002] The explosion of the weapon warhead in the air will generate blast shock waves and high-speed fragments in the air, seriously threatening personnel and military and civilian related facilities. Underwater explosions are prone to produce loads such as blast shock waves, high-speed fragment penetration, and bubble pulsating jets. Among them, the peak pressure of the shock wave load of the underwater explosion is large, the action time is short, and the impact velocity of the fragments is high. Under the coupled loading of the shock wave and the hig...
