摘　　要：分析了PELE的作用机理和剩余速度计算方法,设计了口径为12.7 mm的PELE战斗部和厚度为10 mm的复合靶板。应用ANSYS/AUTODYN有限元数值模拟软件,对以装甲钢为面板和背板,分别使用间隙结构、聚碳酸酯夹层、聚氨酯夹层和橡胶夹层四种结构的复合靶板,初速1000 m/s,垂直入射的PELE侵彻复合靶板过程进行数值模拟。测量了侵彻后复合靶板背板的开孔孔径,综合弹丸侵彻过程不同时刻的复合靶板状态,分析侵彻后复合靶背板的孔径可知,PELE战斗部对聚碳酸酯夹层复合靶板的横向作用较小;,抗弹性能结构最好的复合靶板是聚碳酸酯夹层,其次是间隙结构,最后是橡胶夹层和聚氨酯夹层。In order to study the lateral damage ability of aluminum core Pele warhead to composite armor,firstly,the action mechanism and residual velocity calculation method of Pele are analyzed,and the Pele warhead with diameter of 12.7 mm and composite target plate with thickness of 10 mm are designed.Using ANSYS/AUTODYN finite element numerical simulation software,taking armor steel as panel and back plate,and using composite target plates with gap structure,polycarbonate sandwich,polyurethane sandwich and Rubber Sandwich respectively,the process of Pele penetrating composite target plate with initial velocity of 1000 m/s and vertical incidence is numerically simulated.The hole diameter of the back plate of the composite target after penetration is measured,and the changes of the composite target at different times during the penetration process of the projectile are synthesized.From the hole diameter analysis of the back plate of the composite target after penetration,the lateral effect of Pele warhead on the polycarbonate sandwich composite target is small;For targets with different structures,the sandwich with the best ballistic performance is polycarbonate,followed by the composite target with gap structure,and finally the composite target with rubber and polyurethane.
