摘　　要：为研究钼在药型罩上的应用,运用ANSYS/LS-DYNA有限元软件,对药型罩不同结构参数进行数值仿真,并采用多物质ALE算法模拟射流侵彻钢靶过程。研究结果表明:采用变壁厚结构圆锥罩,装药直径为126 m时选择顶部壁厚2mm、底部壁厚1.5 mm,壁厚变化率为0.7%,为最优壁厚;选择锥角为60°,最高头部速度可达12.0 km/s以上,形成最大有效射流长度为1 161.09 mm;侵彻500 mm装甲钢靶,250 mm处为最佳炸高。与铜相比,钼药型罩形成射流侵彻能力优于铜。In order to study the application of molybdenum in the shaped liner,the numerical simulation was conducted by FEM software ANSYS/LS-DYNA3 D for the structure parameters of shaped charge jet formation,and the process of penetrating steel target was simulated with the ALE method. The results show that for the cone-shaped liner with variable wall thickness and the charge diameter is 126 mm,the optimal thickness is as followings：top 2 mm,bottom 1.5 mm,the change rate of wall thickness0.7%. For the cone angle of 60 degrees,the head speed reaches 12.0 km/s,the maximum effective jet length is 1 161.09 mm. The optimum blasting height is 250 mm for penetrating steel target with 500 mm thickness. Compared with copper,jet formation and penetration capability of molybdenum shaped liner is better than that of copper shaped liner.
