摘要
根据钢筋混凝土目标的特点,提出了一种高速杆流与低速杆流相结合的新型串联聚能装药结构。利用有限元软件分别对前级装药、后级装药的成型过程进行了数值仿真。在此基础上开展了系列串联聚能装药毁伤钢筋混凝土目标的静破甲实验。结果表明:该串联装药可有效提高对钢筋混凝土目标的毁伤能力,能起到对钢筋混凝土的扩孔作用。实验和数值仿真计算结果都表明该串联装药在对付钢筋混凝土、机场跑道、多层间隔靶等反硬目标串联型战斗部中有较好的应用前景。
A new type tandem shaped charge warhead, which produces a high-velocity jet and low-velocity jetting projectiles, was proposed based on the characteristics of a reinforce concrete target. The formation processes of the prepositioned charge and rear-mounted charge were simulated by the three-dimensional finite element dynamic code LS-DYNA3D. Series static armor-piercing tests were carried out to validate the performance of the proposed tandem shaped charge and in the experiment it penetrated a reinforce concrete target and a 45 steel target. Experimental results reveal that the proposed tandem shaped charge can do more damage to reinforce concrete target and drill a larger hole in it than the conventional tandem shaped charge. Experimental and simulated researches show that the new tandem shaped charge has promising applications to the tandem shaped charge warheads against hard objects such as reinforce concrete targets, airdrome runways, multi-plate spaced targets.
