摘　　要：通过有限元显式动力分析软件的显式算法,对工程普遍使用的某一型号石油射孔弹装药爆破的聚能射流形成过程和对射孔枪壁的侵彻作用进行了数值模拟,对其模拟结果进行了讨论。分析了与破甲深度密切相关的炸高参数的特性。计算结果与射孔枪聚能射流形成及破甲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,可用于聚能装药的优化设计,对石油射孔弹生产及科研有一定的作用。Numerical simulation of the shaped charge jet formation process and penetration through the wall of perforating gun are made by use of the explicit dynamic finite element analysis program.And the results of numerical simulation are discussed.The distribution character of the parameter,which is called height of burst,is analysed.The results of numerical simulation are agreement with physical phenomena and laws of jet formation and penetration.The study indicates that the calculation model and simulation method are reasonable and feasible, so can be applied to the optimizing design for shaped charge jet ,which may be used for reference to manufacture and scientific research of perforating bullet.
