摘要:
为了分析靶厚对横向效应增强型侵彻体(PELE)作用效果的影响,采用改变靶板厚度的方法,对PELE以固定速度垂直撞击靶板进行了数值仿真和实验验证。结果表明:随着靶板厚度的增加,穿过靶板弹体的轴向剩余速度呈缓慢下降趋势,破片径向速度呈先增大后减小的趋势;当靶板厚度增大到一定程度时,弹丸的能量大部分耗散在穿甲过程中,横向效应显著减弱。对某一既定的弹靶系统而言,存在最利于PELE发挥横向效应的靶板厚度。
Abstract:
To analyze the influence of target thickness on the lateral effect of PELE(Penetrator with enhanced lateral effect),by changing target board thickness,simulations and experimentations are carried out on PELE impacting target perpendicularly in the same speed.The results show that,after drilling through a target,the residual axial velocity of the penetrator tends to slow down as the target thickness increases,while the biggest radial velocity of debris augments first and diminishes gradually.When the target thickness goes up to some extent,the projectile loses the most of its energy during perforating and the lateral effect weakens remarkably.For a given system,in which PELE and target are unaltered,there is optimal thickness of the target for PELE exerting its lateral effect.
