摘　　要：针对半穿甲战斗部对带有复合材料层的舰船薄钢靶的侵彻作用,采用数值模拟的方法,结合已有实验数据,分别进行不同形状弹头对船用薄钢靶侵彻效应的影响分析、卵头弹对带有复合材料层以及带有加筋结构的船用薄钢靶的侵彻效应分析。实验证明德玛尔公式在大质量弹体侵彻舰船薄钢靶计算中的适用性,并得到3种形状弹头极限侵彻速度的关系;超高分子量聚乙烯层(UHMWPE)仅对低速弹丸阻碍效果明显;加筋结构可降低大质量弹体侵彻舰船薄钢靶的剩余速度,但影响有限。Penetration of semi armor piercing warhead to thin steel targets with composite layers,the numerical simulation method and the experimental data were used to analyze the impact of warheads with different shapes on the penetration effect of ship's thin steel targets,and the penetration effect of oval warheads on ship’s thin steel targets with composite layers and stiffened structures.The applicability of Demar's formula in calculating the penetration velocity of large mass projectiles into ship's thin steel targets was proved,and the relationship among the ultimate penetration velocity of three types of warheads was obtained.UHMWPE layers only had obvious hindrance effect on low-speed projectiles.The reinforced structure could reduce the residual velocity of large mass projectiles penetrating thin steel targets,but the effect was limited.
