摘要
为研究药型罩结构对线型聚能装药的影响,采用有限元软件LS-DYNA对不同截顶高度的锥顶、平顶与圆顶结构的线型聚能装药侵彻45 钢靶板的过程进行了仿真分析.结果表明:不同结构的线型药型罩对线型聚能装药射流的成形与侵彻性能造成较大影响;平顶结构线型聚能装药在截顶高度为16 mm时有最优侵彻性能,较锥顶结构最大侵彻深度提升6.3%;圆顶结构线型聚能装药在截顶高位为10 mm时有最优侵彻性能,较锥顶结构最大侵彻深度提升15.6%.
Abstract
In order to study the influence of the structure of linear shaped charge,the finite element software LS-DYNA was used to simulate the process of linear shaped charge penetrating the 45 steel with different truncation heights of conical,flat and domed structures.The results show that:the shape and penetration performance of the linear shaped charge jet are greatly affected by the different structure of the linear shaped charge liner;The flat top linear shaped charge has optimum penetration performance at truncation height of 16 mm,with a 6.3% increase in maximum depth of penetration compared to the conical top structure;The domed top linear shaped charge has optimum penetration performance at a truncation height of 10 mm,with a 15.6% increase in maximum penetration depth compared to the conical structure.
