| 摘 要： | 在试验的基础上结合有限元计算软件LS-DYNA,采用Lagrange算法对D型战斗部破片飞散及破片毁伤靶板的过程进行了数值模拟,分析研究了D型双层壳体预制破片战斗部破片飞散的特性。与试验结果及ALE算法计算结果的比较表明,采用Lagrange算法模拟预制破片战斗部的破片飞散过程更具合理性和有效性。

| Abstract: | Numerical simulation of the working process of warhead has important significance to the design of deformable warhead.Fragment distribution and destroy effect of a premade D-shape warhead were obtained experimentally.Base on the experiment,numerical simulation of the experimental process was done by use of Lagrange arithmetic with the finite element software LS-DYNA.The working process of the premade two-layer fragmental warhead in shape of D was analyzed.The simulation result was compared with experimental... |
