为克服目前普遍采用的钨合金壳体的PELE侵彻能力不足、靶后破片形状不规则等问题，提出采用集束钨丝复合材料制作PELE壳体，对其穿甲过程进行了试验研究，利用有限元分析软件 ANSYS/LS-DYNA对PELE撞击靶板的动态响应进行了数值仿真，仿真结果与试验结果的对比分析表明：集束钨丝壳体 PELE 在穿透靶板后能产生明显的横向效应；与钨合金壳体PELE相比，集束钨丝壳体 PELE 靶后形成破片速度更高、破片形状更规则，具有更优异的侵彻能力和横向毁伤性能。

Tungsten alloy is adopted as the j acket of penetrator with enhanced lateral effect(PELE) widely,but it has a series of disadvantages,such as inadequate obdurability,irregular shape of fragments.To overcome the problem,tungsten fiber composite was brought forward to produce PELE jacket.The process of PELE with tungsten fiber composite jacket impacting RHA target was studied by experiments.The dynamic response of PELE impacting target was numerically simulated by ANSYS/LS-DYNA.The simulated results were campared with experiment results. Research results show that PELE with tungsten fiber composite can produce obvious lateral effect behind target.Compared to PELE with tungsten alloy j acket,the shapes of kill elements of PELE with tungsten fiber composite j acket are more regular,and their velocities are much higher,and the penetrating performance and lateral damage effect of PELE with tungsten fiber composite j acket are superior.
