摘　　要：为减小由多个爆轰波的相互干扰而引起子弹丸间的发散角,提高MEFP对典型无人机的侵彻能力和打击面积,选用了轴向组合式MEFP战斗部。选取了代表性的“捕食者”无人机为研究对象,应用ANSYS/LS-DYNA就不同变量形成的弹丸对无人机的侵彻性能进行了数值分析。数值模拟结果表明:相比于TNT及B炸药,拥有更高密度和更快爆速的8701炸药对轴向组合式MEFP的成型效果和对典型无人机的毁伤效果更好。并且在特定的装药条件下,轴向组合式MEFP战斗部药型罩壁厚的最佳取值为2.5-3 mm,最佳曲率半径r取72-82 mm。In order to reduce the divergence angle between bullets caused by the mutual interference of multiple detonation waves and improve the penetration capability and attack area of MEFP to typical UAV, an axial combined MEFP warhead was selected. The representative predator UAV was selected as the research object. On this basis, ANSYS/LS-DYNA was used to conduct numerical analysis on the penetration performance of UAV by projectiles formed with different variables. The results show that compared with TNT and B explosives, 8701 explosive with higher density and faster explosion speed has better shaping effect on axial combined MEFP and better damage effect on typical UAV through numerical simulation. Under specific charging conditions, the optimal wall thickness of the axial combined MEFP warhead is 2.5 mm to 3 mm, and the optimal curvature radius r is 72 mm to 82 mm.
