摘　　要：为了研究外壳材料对PELE作用效果的影响,采用不同材料外壳的PELE垂直侵彻装甲钢靶进行试验研究和数值仿真。结果表明,外壳材料的密度和压拉比对PELE的毁伤效果产生重要影响。随外壳材料密度的增大,PELE的存速能力增强;随外壳材料压拉强度比的增大,破片横向效应显著增强。To study the influence of the jacket material on the lateral effect of penetrator with enhanced lateral effect （PELE）, numerical simulation and experiments were carried out on PELE impacting armor steel target perpendicularly with distinct jacket materials. The results show that the density and ratio of the compressive resistance to tensile strength of the jacket material have much to do with the PELE effect. With the increase of the jacket density, the residual velocity of the projectile enhances gradually behind the same target, and the lateral velocity of debris augments when the ratio of the compressive resistance to tensile strength of jacket is growing.
