摘　　要：为了研究药型罩对聚能射流破甲威力的影响,利用LS-DYNA动力有限元计算程序对聚能射流形成过程进行了数值模拟。在此基础上着重应用数值模拟方法分析了药型罩锥角、药型罩壁厚、药型罩形状对聚能射流速度的影响,得到了射流速度与药型罩的关系,射流速度随药型罩锥角的减小而增加,随药型罩壁厚的增加而降低,喇叭形罩比圆锥罩速度大。从而为聚能射流药型罩的设计提供参考。In order to study the effects of liner on shaped charge jet,the process of it has been numerically simulated with LS-DYNA dynamic finite element procedure.In addition,the effects of liner on velocity of shaped charge jet are studied by numerical simulation method.And the relationship between liner and jet velocity is obtained.Jet velocity increases with decreasing the cone-shaped angle and decreases with increasing the wall thickness.The velocity of trumpet liner is greater than cone-shaped liner.The results provide some reference for the design of liner.
