Numerical Simulation of Combined Liner Formation in Water

摘要

摘要: 为提高鱼雷战斗部对大型舰艇的毁伤能力, 提出一种环型-球缺/大锥角组合药型罩作为鱼雷串联战斗部的前级装药结构, 其结构由周向的环型药型罩与中心的球缺罩或大锥角罩组合而成。利用LS-DYNA有限元软件对组合药型罩水介质中的成型机理进行研究, 对比分析2种起爆方式下锥角及曲率半径对中心聚能罩水中成型的影响。仿真结果显示, 环型罩在水中可形成环形射流, 用于目标外壳体切割; 中心罩结构变化对环型罩射流成型影响不大, 中心截顶大锥角罩形成的杆式射流形态细长, 头部速度较高; 球缺罩形成的杆式侵彻体较为粗短, 速度梯度较小。

Abstract: To enhance damage effect of torpedo warhead on large warship, a combined liner with annular-spherical segment/large cone angle structure is taken as the front charging chamber of the torpedo tandem warhead. The combined liner is composed of an annular liner around and a spherical segment liner or a large cone angle liner in the center. The formation mechanism of the combined liner in water is analyzed by the software LS-DYNA. The influences of the cone and curvature radius on the formation of the central liner in water are investigated in two priming modes. Simulation results show that: the annular liner forms annular jet in water to cut first layer of target shell; the change of central liner structure has little influence on jet formation of the annular liner; the long and the thin rod-liked jet formed by the central large cone liner has a high head velocity, while the rod-liked penetrator formed by the central spherical segment liner has a short and thick shape and relatively small velocity gradient.
