摘要
利用有限元软件LS-DYNA,使用流固耦合算法对聚能装药在水下爆炸、射流形成及其在水中的运动进行了仿真,同时也对射流侵彻靶板的过程进行了模拟计算,直观地说明了水下聚能爆破现象,对射流速度、破甲过程进行了深入研究。最后,通过工程试验验证了所设计的结构。试验后射流侵彻靶板所形成的破坏效果明显,满足工程实际要求。
Because of its significant performance advantages, the shaped bursting of the technology has a broad application prospects. In this paper, through the finite element software I_S-DYNA, using the fluid- structure interaction algorithm, shaped charge underwater explosion, jet formation in water sports and charge jets process are simulated, intuitively clarifying researching jet velocity under process. Finally, validated, and the charge jets destructive effect ing. shaped underwater blasting phenomenon and deeply through the engineering test, the design of the structure is after the test meets the practical requirements of engineer-
