摘　　要：为了提高爆炸成型含能侵彻体的侵彻性能,提出一种F型含能罩/金属罩双层药型罩聚能装药结构。采用非线性动力学软件AUTODYN-2D对包覆式含能复合侵彻体的爆炸成型与侵彻过程进行数值模拟,分析F装药下不同内外罩壁厚组合对复合侵彻体成型及侵彻性能的影响。结果表明:随着外层含能罩壁厚的增大,复合侵彻体头部速度增大,长径比先增大后减小,穿靶深度先增大后减小,当内外罩壁厚组合为3mm/3mm时,复合侵彻体穿靶深度最大,相比含能EFP穿靶深度增大约21.07%,并且可对间隔靶目标造成有效毁伤。In order to improve the penetration performance of explosively formed energetic penetrator,a double-layered liner shaped charge structure of F-type energetic liner/metal liner was proposed.The non-linear dynamics software AUTODYN-2D was used to numerically simulate the explosive forming and penetration process of the energetic composite penetrator,and the influence of the combination of different inner and outer cover wall thicknesses under the F charge on the forming and penetration performance of the composite penetrator was analyzed.The results show that as the wall thickness of the outer energetic cover increases,the head velocity of the composite penetrator increases,the aspect ratio and penetration depth first increases and then decreases.When the thickness combination is 3mm/3mm,the penetration depth of the composite penetrator is the largest,which is about 21.07%more than the energetic EFP,and can cause effective damage to the spacer target.
