Penetration Performance of Depleted Uranium Alloys Liner

摘要: 为分析贫铀合金药型罩的破甲性能，以某种结构的紫铜药型罩为比较对象，采取数值仿真的方法设计了贫铀合金药型罩结构，并分别以紫铜和铀铌合金为药型罩材料开展了静爆破甲效应实验，对比了两种材料药型罩形成的射流对45钢棒的侵彻能力。研究结果表明，在主药柱质量相当的情况下，贫铀合金药型罩形成的射流最高侵深较紫铜材料的平均侵深提高约33.4%。Abstract: In the present study, we redesigned the structure of a depleted uranium alloys liner to analyze its penetration performance using numerical simulation results on the basis of a copper liner, and compared the penetration capability of two liners, made of copper and uranium-niobium alloys respectively by penetration experiments.The results show that, with almost the same quality of the main charge, the maximum penetration depth of the depleted uranium liner was 33.4% bigger than that of the copper liner.
