摘　　要：使用LS-DYNA动力分析软件建立包括炸药、药型罩、壳体、靶板、空气在内,用以分析LEFP侵彻性能的三维数值模型。通过考察LEFP与靶板的变形特性、侵彻深度和侵彻体速度随时间变化的规律,分析LEFP侵彻靶板的具体过程,并讨论炸高对LEFP侵彻性能的影响。最后,比较试验与数值计算相关结果,两者吻合较好。Numerical model including liner,shell,target and air was established using LS-DYNA software to analyze penetration capability of LEFP.In order to study the particular process of penetration,the distortion of LEFP and target,the relationship between penetration depth,speed of LEFP and time were analyzed,and the influence of height of burst on penetration capability of LEFP was discussed,the numerical simulation data agrees well with experimental results.
