摘　　要：为了研究铝镁等轻金属作为弹芯对横向效应增强型侵彻体(PELE)的影响,采用显式非线性动力分析软件AUTODYN对内装不同轻金属材料弹丸进行侵彻靶板数值模拟,获得了不同弹体对靶板的毁伤效应。结果表明:填充材料硬度越低,PELE壳体残留越少,锂镁合金适宜作为PELE的填充材料。In order to analyze the influence of the light metal filling material on the Penetrator with Enhanced Lateral Efficiency（ PELE）,AUTODYN explicit nonlinear dynamic analysis software was used to simulate the penetration of PELE filled with different light metal materials against target plate,and the damage effects of different projectile on target plates were obtained. The simulation results shows that the lower hardness of filling material is,the short the length of residual jacket is. Mg-Li alloy is suitable for filling material of PELE.
