A kind of explosive acceleration device and method

Abstract

The application discloses an explosive acceleration device and method, the basic principle of which is to use the electromagnetic track to accelerate the slider and drive the explosive movement, design the slider and shell structure to ensure the safety of the explosive acceleration process, and use the preset at the end of the guide rail to The separation structure realizes the safe separation of the slider, shell and explosives. 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 and method, which are 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 tes...

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. Therefore, an accelerated device and method for explosives are needed to enrich the accelerated test program for explosives. Make up for the deficiencies of existing test devices and provide technical support for better research on the dynamic mechanical properties of explosives
