摘　　要：利用相似理论分析了聚能装药射流侵彻钢板过程的相似参数,建立了射流侵彻钢板的相似关系;并采用LS-DYNA3D软件,对聚能射流侵彻钢板的过程进行了数值模拟。结果表明,射流对模型1、模型2的侵彻深度、开孔口径、射流头部速度、侵彻形状均符合相似律。Using the analogue theory, the analogue parameters of shaped charge jet penetrating steel plate are analyzed and the analogue rela- tions of shaped charge jet penetrating steel plate are established. Then we simulated the process of Shaped Charge jet penetrating the steel Plate, using ANSYS/LS-DYNA software. The result showed that the penetration depth, the speed of jet head and the penetration shape formed from the shaped charge jet to model land 2.
