Experimental device for evaluating explosive loading impact safety of tail part of projectile body

Abstract

The invention discloses an experimental device for evaluating the explosive loading impact safety of the tail part of a projectile body and solves the problem that in the prior art, the explosive loading impact safety of the tail part of the projectile body of a warhead cannot be accurately evaluated. The device comprises a limit barrel body, a drive press block, a shearing die and the like, wherein the drive press block is placed at the upper end of explosive loaded in the limit barrel body and used for applying certain pressure to the explosive; the shearing die is mounted at the bottom end of the limit barrel body in a sleeving manner and used for generating shearing acting force on the explosive. The experimental device is mainly used for experiment research on the self-response of the explosive loading of the tail part of the projectile body of the warhead under shearing action, has a simple structure and is convenient to operate, and can compare the anti-shear ability and the ignition response characteristic of the explosive loading under the same loading condition.

Description

technical field [0001] The invention relates to an experimental device for evaluating the impact safety of explosive charges, belonging to explosive performance testing devices. Background technique [0002] In order to detonate the warhead explosive charge stably and reliably, a convex booster tube is often installed at the tail of the penetrating warhead shell, which becomes one of the important factors leading to the accidental ignition of the explosive charge during the penetrating process. The impact safety performance has always been an important content in the research of this type of ammunition, especially the safety of explosive charges under the condition of external impact has become a hot spot of concern. During the penetration process of the anti-overload projectile, there is a phenomenon of "tail swing" at the tail of the projectile. In addition, there is a booster tube at the tail of the warhead, so the shearing movement of the explosive charge will be more c...

AI Technical Summary

Problems solved by technology

However, the above-mentioned experimental method is only a simple impact loading of explosive grains or tablets, and does not involve the impact of post-impact shear loading on explosives, and cannot evaluate the impact of the complex charge structure (convex structure) at the tail of the projectile on the ignition of explosives.
