Test method and device for dynamic explosion power of explosive shell

Abstract

The invention discloses a test method and device for dynamic explosion power of an explosive shell. The test method and device for the dynamic explosion power of the explosive shell are used for testing the dynamic explosion area of the explosive shell. The test method for the dynamic explosion power of the explosive shell includes that acquiring an upper static explosion scattering angle, a lower static explosion scattering angle and a fragment velocity of a fragment when the payload of the explosive shell performs static explosion, and a fall velocity and a fall angle when performing dynamic explosion; acquiring an upper dynamic scattering angle and a lower dynamic scattering angle when the explosive shell performs dynamic explosion; judging whether the fall angle is larger than the upper dynamic scattering angle, and obtaining the first judge result; when the fall angle is larger than the upper dynamic scattering angle, acquiring the first dynamic explosion area when the explosive shell performs dynamic explosion; otherwise, acquiring the second dynamic explosion area when the explosive shell performs dynamic explosion. By means of the test method for the dynamic explosion power of the explosive shell, the dynamic explosion area of the explosive shell under the motion state is acquired, the dynamic explosion power of the explosive shell is reflected, the explosion situation of the explosive shell under the motion state can be precisely acquired, reliable help is provided for realizing the true performance of the explosive shell, and the problem that the static explosion test cannot really reflect the explosion performance of the explosive shell under the motion state is solved.

Description

technical field [0001] The present application relates to the field of shell testing, in particular to a method and device for testing the dynamic explosion power of shells. Background technique [0002] In military applications, artillery shells can use the fragments produced by the explosion, explosion products and explosion shock waves to achieve the purpose of killing the enemy's vital forces and blasting the enemy's fortifications. Existing methods for testing the power of shells are generally tested by means of static explosion, that is, the warhead of the shell is vertically placed on the bullet rack with the bullet point upwards, and a certain distance is set between the center of mass of the warhead and the ground. A wooden or steel target plate of a certain shape is arranged on the ground. After detonating the shell warhead, the effective killing radius, dense killing radius, armor-piercing ability and arson ability of the bomb are determined according to the numbe...

Problems solved by technology

[0003] However, such a static explosion test method is carried out under the condition that the shell and the ground are relatively static, while in actual combat, the shell is in a state of relative motion to the ground when it explodes after being fired, and the shell explodes and explodes in a moving state. The lethality produced by the explosion in the static state is different. The technical indicators obtained in the static explosion mode cannot reflect the real lethality of the shell when it explodes in the moving state, that is, there is a significant difference between the static explosion power and the dynamic explosion power of the shell.

[0004] In the prior art, there is no method for testing the explosive power of shells, therefore, there is an urgent need for a method for testing the dynamic explosive power of shells
