摘要： 综合运用理论分析、仿真计算和试验研究，优化设计了实现杆式射流（JPC）与射流(JET)转换的双模战斗部。理论分析了单点起爆与环起爆条件下药型罩压垮变形情况，数值仿真优化了成型装药结构参数，包括药型罩锥角、药型罩弧度半径、药型罩壁厚和装药高度，找出了实现JPC与JET双模转换的起爆方式及结构参数匹配关系：采用单点起爆形成JPC，环起爆形成JET，选取药型罩锥角为80°~100°，药型罩弧度半径为0.1倍装药口径，药型罩壁厚匹配锥角设计，装药高度为0.9倍装药口径。针对优化结构进行了X光成像试验研究，试验结果与仿真结果误差在8%以内。综合运用理论分析、仿真计算和试验研究，优化设计了实现杆式射流（JPC）与射流(JET)转换的双模战斗部。理论分析了单点起爆与环起爆条件下药型罩压垮变形情况，数值仿真优化了成型装药结构参数，包括药型罩锥角、药型罩弧度半径、药型罩壁厚和装药高度，找出了实现JPC与JET双模转换的起爆方式及结构参数匹配关系：采用单点起爆形成JPC，环起爆形成JET，选取药型罩锥角为80°~100°，药型罩弧度半径为0.1倍装药口径，药型罩壁厚匹配锥角设计，装药高度为0.9倍装药口径。针对优化结构进行了X光成像试验研究，试验结果与仿真结果误差在8%以内。

Abstract: Summing up the theory analysis, simulation calculation and test study, this paper optimized the dual-mode warhead to achieve the conversion of jetting projectile charge(JPC) and jet (JET). It was analyzed the liner collapse situation under single point detonation and annular detonation by the theory, and optimized the shaped charge parameters, such as liner cone, radian radius, thickness and charge height, by the numerical simulation. Then, it obtained the initiation mode and the matching relations of the shaped charge parameters which could get the conversion between JPC and JET. The JPC was formed by single point detonation, and the JET was formed by annular detonation. The liner cone was chosen 80°~100°, the liner radian radius was 0.1 time charge caliber, the liner thickness was designed in accordance with liner cone, and the charge height is 0.9 time charge caliber. Aimed at the optimal structure, the X-ray imaging test was done, and the error between the test and simulation results is within 8%.
