| 摘 要： | 针对聚能装药爆破存在的问题，提出一种利用计算机对聚能装药爆破进行数值模拟的方法。通过有限元显式动力分析软件的显式算法对石油射孔弹圆锥型聚能装药爆破形成射流的过程进行数值模拟，分析了圆锥型聚能装药的射流速度的分布特性，并与带外壳的聚能装药的射流过程的模拟结果进行了对比。计算结果与圆锥型聚能射流的物理现象和规律相吻合，说明该计算模型和模拟方法合理、可行，对石油射孔弹生产及科研有一定的借鉴作用。

| Abstract: | A numerical simulation method by computer is present in order to solve the problem during the shaped charge blasting. Numerical simulation of the conical shaped charge jet formation process is made by use of the explicit dynamic finite element analysis program. The distribution character of velocity of shaped charge jet is analyzed,and the results between shelled model and no shell one are compared. The results of numerical simulation are in agreement with physical phenomena and laws of jet formed by conica... |
