Dynamic detonation power field test system and test method for destruction detonation grenade

Abstract

The embodiment of the invention provides a dynamic detonation power field test system and test method for a destruction detonation grenade, and belongs to the technical field of damage evaluation. Thedynamic detonation power field test system for the destruction detonation grenade involves a trigger target, a sector plate and a shock wave pressure detection device; the trigger target is arrangedopposite to a ballistic mortar, and the ballistic mortar is used for launching the destruction detonation grenade; the sector plate is arranged at one side of the trigger target and protrudes in a direction away from the trigger target, and fragments generated after the destruction detonation grenade detonates penetrate into the sector plate; and the shock wave pressure detection device is arranged at the other side of the trigger target and is used for detecting a pressure signal generated by a shock wave after the destruction detonation grenade detonates. According to the technical scheme, the distribution rules of the fragment power field and the shock wave power field of the destruction detonation grenade under the dynamic detonation state can be detected, and the distribution rules include the fragment scattering condition, the shock wave overpressure distribution condition and the like.

Description

technical field [0001] The invention relates to the technical field of damage assessment, in particular to a test system and a test method for the dynamic detonation force field of an anti-explosive grenade. Background technique [0002] Anti-explosive grenade is a shell that relies on fragments and shock waves generated by explosives to kill or destroy targets. It is the most basic type of ammunition used by modern artillery. It uses fragments and shock waves generated after the explosion of projectiles to kill or blast. [0003] The acquisition of the power field of the anti-explosive grenade can provide important support for the structural design, performance evaluation and combat use of the anti-explosive grenade; Vector synthesis is used to study the scattering law of fragments after the explosion of moving projectiles. Since the scattering speed of thousands of fragments is difficult to be accurately obtained through experiments, the dynamic fragmentation zone of fragm...

AI Technical Summary

Problems solved by technology

[0004] Among the many types of anti-explosive grenades, large-caliber anti-explosive grenades are different from precision strike ammunition and have low shooting accuracy. This characteristic determines that it is difficult to accurately predict the impact point like precision-guided ammunition. Power test targets and sensors are arranged near it for Testing ammunition force fields that reflect real ballistic fall velocities
