摘　要：利用ANSYS／LS-DYNA 软件对某特定结构小锥角药型罩聚能装药在顶部内圆弧半径不同的情况下射流的形成过程及侵彻装甲钢进行数值模拟。仿真结果表明，在小锥角药型罩口径、材料及壁厚确定的情况下，随着顶部内圆弧半径的增大，射流的长度、头部速度逐渐减小，长径比逐渐增大；射流侵彻装甲钢开孔口径逐渐增大，但对靶板的侵彻深度降低。

Abstract：The formation process of jet and its penetration into armored steel of shaped charge with small cone angle liner with different top arc radius were simulated by ANSYS／LS-DYNA software.The simulation re⁃sults show that when the diameter，material and wall thickness of the small cone angle liner are determined，the length and velocity of the jet decreases gradually with the increase of the top arc radius，and the ratio of length to diameter increases gradually.

Keywords：inner arc radius；small cone angle shaped charge；jet formation；penetration；numerical simula⁃tion
