摘要

摘要: 为了研究钽合金爆炸成型弹丸(EFP)对双壳潜艇含水复合装甲(由非耐压壳、耐压壳和水夹层组成)的毁伤效果, 文章对含水复合装甲在钽合金 EFP 作用下的毁伤效果进行了数值仿真与试验, 并与相同装药结构形成的铜 EFP 数值毁伤结果进行对比。结果表明, 钽合金EFP在穿透3mm 45钢非耐压壳和680mm水层后仍有剩余动能作用于12mm 45钢耐压壳, 使之产生隆起变形, 但未能穿透; 而铜EFP在穿透非耐压壳后未能穿透水层。数值仿真与试验结果较吻合, 证明钽合金相比铜更适合用作水下EFP战斗部药型罩材料。

Abstract: To study the damage effects of tantalum alloy explosively formed projectiles(EFPs) on the water-partitioned armor of submarines with double-layer armor(composed of a non-pressure-resistant hull, pressure-resistant hull, and water interlayer), numerical simulations and experiments were conducted, and the results were compared to numerical damage results for copper EFPs formed using the same charge structure. The results demonstrate that after penetrating a 3 mm non-pressure-resistant hull made of #45 steel and a 680 mm water layer, the tantalum alloy EFP still had residual kinetic energy acting on a 12 mm pressure-resistant shell made of #45 steel, which caused uplift deformation, but failed to penetrate. The copper EFP failed to penetrate the water layer after penetrating the non-pressure-resistant hull. The numerical simulation results are in good agreement with the experimental results, which proves that tantalum alloy is more suitable than copper as a liner material for underwater EFP warheads.
