防跳弹结构对弹体侵彻性能的影响

Influence of Anti-Bounce Structure on Penetration Performance of Projectile

为获取弹体侵彻不同目标靶时,防跳弹结构对其侵彻能力的影响规律,设计了含防跳弹结构的实验弹,并对其进行了侵彻钢板和混凝土靶实验,获取了防跳弹结构及其位置对目标靶破坏形态、剩余速度的影响规律。结果表明:含防跳弹结构实验弹未改变钢靶和混凝土靶的破坏模式;实验弹侵彻钢靶后的剩余速度随防跳弹结构与弹尖间距的增加而减小;而侵彻素混凝土靶时,则表现出相反的趋势,这是由于不同目标靶破坏模式的差异引起的。

In order to obtain the influence law of the anti-bounce structure on the penetration ability of the projectile when it penetrates into different targets,the experimental projectiles with the anti-bounce structure were designed.The penetration experiments of steel plate and concrete targets were carried out,and the influence law of the anti-bounce structure and its position on the target damage pattern and residual velocity were obtained.The results show that the failure modes of steel target and concrete target are not changed by the experimental projectile with anti-bounce structure;The residual velocity of the experimental projectile after penetrating the steel target decreases with the increase of the distance between the anti-bounce structure and the bullet tip;When the projectile penetrates the plain concrete target,it shows the opposite trend,which is caused by the difference of failure modes between steel target and concrete target.
