摘要
为研究反跑道串联子弹药后级随进战斗部在前级聚能开孔战斗部预先开出孔道情况下对机场跑道的随进侵彻性能,采用LS-DYNA动力学仿真分析软件分别对随进弹在不同随进速度,不同攻角及不同介质界面的条件下侵彻跑道的过程进行数值模拟,所得结果得到了理论分析和样弹实验的验证。研究结果对反跑道串联随进弹的设计具有参考价值。
The characteristics of penetrating an runway obliquely by using projectiles with anti-runway tanckem warheads were studied,under the holed in advance condition of an airport runway penetrated by the former stage warheads.The penetrative process of the tandem warheads was simulated with the finite element code LS-DYNA3 D, considering the different influencial factors,such as,speed,attack angle and medium interface.The results were validated with live ammunition experiments.The study results provided a reference for design of anti-runway tandem projectiles.
