摘　　要：运用ANSYS/LS-DYNA仿真软件,分析了一种次口径三层球缺药型罩战斗部形成串联EFP的过程,得到每层药型罩形成的EFP速度和长径比随球缺罩曲率半径、药型罩壁厚、装药高度的变化规律曲线。分析结果表明:球缺罩曲率半径和药型罩壁厚对EFP外形有显著影响,装药高度的增加可有效提高EFP速度。By ANSYS/LS-DYNA software,the forming process of shaped charge with triple sub-caliber hemispherical liner into series EFP was analyzed. The law curves of velocity and L/D with structural parameters of curvature radius,thickness of hemispherical liner and the height of shaped charge of each liner were obtained. The result indicates that there are remarkable effects of curvature radius and thickness of hemispherical liner on the formation parameters of each EFP. Increasing the height of shaped charge effectively enhances velocity of each EFP.
