摘　　要：为研究药型罩形状参数对EFP速度的影响,在理论分析的基础上,设计了口径、高度及质量均相同的锥角罩和球缺罩两种典型药型罩。利用软件对两种典型药型罩在同样的装药高度下的形成爆炸成形弹丸的过程进行仿真,仿真计算结果与理论计算结果比较吻合。对两模型中的径向及轴向速度进行对比分析,结果表明相同条件下药型罩形状对EFP最终速度影响不大,速度差异主要是药型罩形状引起的装药利用率不同导致的。To investigate the influence of liner on velocity of explosively formed penetrator （ EFP）, two kinds of classic liner are desighed ： apex angel liner and sphere liner based on analysis of associated theories , and they have same diameter,height and mass. The advantage of the explicit finite element program to simulate the process of EFP formation is taken, the calculation fit well to the theory. Then their velocities of x-axis and y-axis and draw the conclusion are compared ： the shape of liner affect the final velocity of EFP a little and the difference between them is mainly brought about by the different availability of charge caused by liner shape.
