Description

Technical Field

[0001] The present invention relates to the field of high-speed projectile injury, and in particular to an injury system and an injury method for simulating ultra-high-speed projectiles. Background Art

[0002] Currently, pipelines or storage tanks are used for storage or transportation in many fields such as gas, oil and liquefied gas. Since pipelines or storage tanks are filled with a large amount of high-pressure gas, if a gas or oil storage tank explodes, the tank will decompose into a large number of fragments under the high-speed and high-pressure gas, threatening people's lives and causing casualties. If timely and effective rescue measures are not taken, the casualties will be aggravated.

[0003] In addition, in modern military simulation training environments, the lethal weapons used are filled with gunpowder. When the gunpowder in a sealed environment is ignited, the expanding gas cannot disperse and will tear the sealed shell apart, causing an explosion. After the explosion, the shrapnel inside will be irregularly shaped and fly out in all directions within an effective radius. A large number of high-speed fragments will fly in all directions. These high-speed flying fragments will cause damage to the organism. If timely and effective first aid measures are not taken, it will seriously threaten the vital signs of the organism.

[0004] In view of the above-mentioned situation where a large number of high-speed fragments generated by high-speed, high-pressure gas explosions cause casualties to organisms, medical staff are currently unable to make an accurate assessment of the injury status of the organisms, and are also unable to provide timely and effective rescue measures; therefore, in order to enable organisms to obtain rapid and effective rescue measures and rescue plans when they are injured by high-speed projectiles or fragments, it is necessary to design a simulation device that can be used in the laboratory to simulate and restore the injury status of the organism under the impact of high-speed projectiles or fragments, and provide more realistic experimental data and experimental conditions for medical research. Summary of the invention

[0016] The two ends of the pump pipe are fixedly mounted on the fixed base through a first fixing bracket and a second fixing bracket respectively;

[0017] The launch end movable slide rail is provided with a launch tube movable bracket and an experimental cabin movable bracket; the launch tube is provided on the launch tube movable bracket and can move along the launch end movable slide rail through the launch tube movable bracket; the experimental cabin is provided on the experimental cabin movable bracket and can move along the launch end movable slide rail through the experimental cabin movable bracket. Furthermore, a drive limit plate is provided at the front end of the drive movable slide rail to prevent the drive movable bracket from sliding out of the drive movable slide rail;

[0027] At the same time, the present invention also proposes a method for simulating the injury caused by a hypervelocity projectile, based on the above-mentioned system for simulating the injury caused by a hypervelocity projectile, which is special in that it includes the following steps:

[0029] Step 2: Connect the launch drive assembly, pump tube, projectile mount, launch tube and experimental cabin in sequence;

The speed and pressure of the test projectile when it collides with the organism are detected by the detection device in the experimental cabin, and the injury law of the test projectile is obtained, thus completing the simulation of the injury state when the hypervelocity projectile collides with the organism.

[0033] Beneficial effects of the present invention:

[0034] [1] The injury-causing system for simulating a hypervelocity projectile of the present invention has a simple structure. It provides high-speed motion power for the test projectile by means of a firing drive assembly, and increases the motion speed of the test projectile by means of compressing the inert gas in the pump tube, so that the test projectile causes injury to the organism at an exit speed of several thousand meters per second, thereby highly restoring the injury state when the test projectile hits the organism at high speed.

[0035] [2] The present invention can effectively absorb the impact force of the piston on the launch tube by arranging a buffer connection section on the outlet end of the pump tube, thereby improving the safety performance of the injury system and the validity of the test data.

[0036] [3] The present invention assembles the launch drive assembly, pump tube, launch tube and experimental cabin through the provision of a launch end movable slide rail and a drive movable slide rail, which can effectively save the assembly time of the system, improve the assembly efficiency, ensure the stability and reliability of the system structure assembly, and also facilitate the disassembly and maintenance of the system structure.

[0037] [4] The present invention can simulate the injury patterns of organisms under different atmospheric pressure environments by setting up a vacuum simulation system on the experimental cabin, thereby improving the application scope of the system simulation and providing effective reference data for medical staff on the injury conditions of organisms under different environments.

[0038] [5] The present invention makes the diameter of the piston match the inner diameter of the pump tube, so that the piston can play a good sealing role in the pump tube, thereby improving the gas compression efficiency; during the launch process of the system, when the piston passes through the buffer connection section on the outlet end of the pump tube, the buffer connection section can effectively reduce the damage of the piston to the pump tube and the launch tube.

[0039] [6] The present invention can quickly provide a large driving force to the piston in the pump tube through the quick-opening valve driving device, thereby causing the piston to quickly compress the gas in the pump tube, thereby generating high-speed motion power for launching the projectile to be tested; at the same time, the movement speed of the projectile to be tested can be adjusted by controlling the driving force of the quick-opening valve driving device, thereby providing more comprehensive test data for the injury system, effectively improving the scope of application and practicality of the system.
