摘要

摘要: 利用轻气炮进行卵形头、平头以及半球形头杆弹正撞击等厚接触式叠层靶实验，得到这3种结构的初始速度-剩余速度曲线以及弹道极限，对回收靶体进行分析，研究分层数对叠层靶抗侵彻性能和失效模式的影响。结果表明：对于延性金属薄板，分层结构降低靶体的弹道极限，单层板的抗侵彻性能高于叠层板的抗侵彻性能。对于平头弹和卵形头弹，弹道极限随分层数的增加而降低；对于半球形头弹，弹道极限随分层数的增加先降低后升高；分层数对弹道极限的影响随弹体初始撞击速度的增加而减小。

Abstract: Layered plates are normally impacted by ogival, blunt and hemispherical projectiles using a gas gun to investigate the influence of the number of layers on the ballistic resistance and target failure model. The residual velocity versus the initial velocity curves for the projectiles are constructed, and ballistic limit velocities are obtained. Based on the experimental data, the monolithic targets show greater ballistic limit velocity than multi-layered targets. For blunt and ogival projectile, the ballistic limit velocity decreases with increasing of the number of layers. However, for hemispherical projectile, the ballistic limit velocity firstly decreases and then increases with the increase of the number of layers. The influence of layering decreases as the impact velocity of projectile increases.
