Explosive acceleration device

Abstract

This application discloses an explosive acceleration device, the basic principle of which is to use electromagnetic rails to accelerate the slider and drive the explosive movement, the slider and shell structure are designed to ensure the safety of the explosive acceleration process, and the separation structure preset at the end of the guide rail is used Safe separation of slider, housing and explosives is achieved. This application has the advantages of high test safety and low test cost, can meet the accelerated test requirements of most explosives, and can provide technical support for the development of anti-overload explosives, insensitive explosives, and explosive safety evaluation tests.

Description

technical field [0001] The application belongs to the technical field of explosive performance parameter experiments, and relates to an explosive acceleration device, which is mainly used for explosive impact performance tests, and can provide technical support for the design of anti-overload explosives and insensitive explosives. Background technique [0002] Explosives are the damage energy of conventional weapons and ammunition. Explosives are widely used in various types of penetrating ammunition and artillery-launched ammunition. These ammunition will encounter a large overload condition of tens of thousands of gravitational accelerations during use. Therefore, it is necessary to fully Consider the anti-overload performance of explosives. In order to be able to simulate the overload environment of ammunition, researchers have established a large number of explosive accelerated test devices, such as light gas guns, artillery, rocket skids, etc., but these test devices ca...

AI Technical Summary

Problems solved by technology

[0003] (1) The single test cost of the rocket skid exceeds nearly one million RMB, which is difficult to be used in conventional scientific research. The accelerated impact test method of explosives established based on the principle of relative motion cannot completely replace the direct accelerated test method of explosives;

[0004] (2) At present, there is no way to realize the safe and reliable direct acceleration test of the bare grain, and the impact dynamic mechanical properties of the bare grain of the explosive cannot be directly measured;

[0005] (3) The acceleration process of explosives is a black box, and it is difficult to analyze the cause of the accident if there is a bombing event

[0006] The impact dynamic mechanical properties of explosives is one of the core issues in the design of anti-overload explosives and insensitive explosives. At present, there are certain limitations in the accelerated test device for explosives. Insufficient test equipment provides technical support for better research on dynamic mechanical properties of explosives
