摘要

摘要: 基于60 mm弧锥结合罩爆炸成型弹丸（EFP）装药，设计了一种在药型罩前适当位置安装可抛掷的十字形网栅的切割式双模战斗部结构，其具有生成单个EFP或者多爆炸成型弹丸（MEFP）的功能；根据目标属性，可选择性地改变战斗部的毁伤元成型模式，实施最有效的打击。利用LS-DYNA程序，对两种模式毁伤元成型及侵彻45钢靶过程特性进行了数值模拟，模拟结果与地面静爆实验结果吻合较好。研究表明，该战斗部形成的单个EFP能贯穿25 mm厚45钢靶，可有效打击重装甲目标；经网栅切割后能形成5片具有一定质量和方向性、可贯穿6 mm厚45钢靶的EFP破片，显著提高了对轻装甲目标的毁伤概率。

Abstract: We studied an optional/dual-mode warhead with an ejectable cross-shaped cutting reseau fixed at a proper place before the liner to realize multi-function of ammunition based on 60 mm arc-cone liner Explosive Formed Projectile (EFP) charge configuration. The optional/dual-mode warhead can change the kill elements mode according to the target properties (heavily or lightly armored targets), and can form single EFP or MEFP (Multiple Explosively Formed Projectile) to provide the most effective attack. The whole process of formation, flying and penetration of single EFP and MEFP was simulated using LS-DYNA3D. The simulation results are in good agreement with the experimental data. This study indicates that the single EFP has a good aerodynamic stability at a velocity of 1 508 m/s and it can penetrate through the 45 steel targets with a thickness of 30 mm; While the MEFP has a velocity between 1 500 and 1 750 m/s with an even distribution and can penetrate through the 45 steel targets with a thickness of 6 mm. The obtained results provide important reference to the design of dual-mode warhead.
