摘　　要：采用AUTODYN-2D软件对内核材料为高密度聚乙烯、Kevlar-Epoxy、Glass-Epoxy、尼龙、铝、铜的钨壳体PELE弹丸以不同速度侵彻厚50mm的铝靶过程进行了数值模拟。得到了装填不同内核材料PELE弹丸的横向效应随着速变化的规律。铝、高密度聚乙烯以及尼龙作为内核材料均有良好的横向效应,壳体有效破碎段长度可根据弹丸发射速度调节。研究结果为PELE弹药设计的材料、速度选取提供了参考。Penetration process of penetrator with enhanced lateral effeet（PELE） in 50mm aluminum alloy target in different velocities were simulated by AUTODYN-2D code. Lateral effect of PELE of Tungsten alloy shell filled with Polyethylene, Kevlar-Epoxy, Glass-Epoxy, Nylon, Aluminum, copper were calculated to achieved the tendency of lateral effect from different filler at various velocities. Aluminum, Polyethylene and Nylon as filler perform very well in lateral effect, the length of fragmentation can be modulated through the fire velocity of shell. The result is useful in choosing material and velocity in engineering design of PELE.
