| 摘 要： | 为了研究单锥罩、双锥罩、球缺圆锥组合罩三种不同的聚能装药结构。利用Truegrid和有限元软件LS-DYNA对三种结构装药的射流形成和侵彻过程进行数值模拟。计算结果表明,双锥药型罩的侵彻效果更好些,但是,在大炸高情况下,射流的尾部容易断裂,影响射流的侵彻效果。

| Abstract: | In order to study the single-cone liner charge,double-cone liner charge and the combination of cone and hemisphere liner charge,truegrid and the finite element software LS-DYNA are used and jet formation and penetration process on the three kinds of structure are cimulated.The results show the double-cone shaped charge has the better penetration effect,but in the big blow of high case,it is easy to break off for the jet＇s tail,affecting the penetration effect. |
