摘　　要：通过实验以及数值模拟,开展了防雷舱结构在聚能装药水下爆炸作用下的毁伤研究,探讨冲击波在多介质结构中的传播规律及其对结构的毁伤机理。结果表明:相同爆炸当量条件下,爆破型装药仅对空舱产生破坏,防雷舱的多介质复合结构对冲击波具有较强的衰减作用,聚能型装药形成的侵彻体可造成液舱前板及后板的穿孔,孔径约为装药直径的1/3~1/2。加宽液舱以及加厚液舱后板可以增强防雷舱的抗爆能力。In this paper,experiments and numerical simulation were conducted to study the damage effect of shaped charges exploding underwater on cabins near the shipboard,and discussed the propagation law of shock wave in multimedia structure and damage mechanism of the structure,providing reference to the design of protective structures.Results show that under the same explosive equivalent condition,explosives can only damage the first cabin of the cabins near the shipboard,the multi-media structure has a strong attenuation effect on shock wave,and the penetrator formed by shaped charge can cause perforation of front board and back board of the second cabin.The diameter of the hole is 1/3-1/2 of the charge.The enlargement of the liquid tank or the thickening of the liquid tank backboard can enhance the anti-explosion ability of the cabin near the shipboard.
