摘　　要：为研究聚能装药最佳炸高的设计方法.通过试验获得34°与40°两种上锥角双锥形药型罩聚能装药在6.0,6.5,7.0,7.5和8.0倍炸高条件下的静破甲深度;同时,进行了同实验工况的数值模拟方法研究;在数值模拟方法获得验证后,通过数值模拟获得了不同上锥角下炸高对双锥罩聚能装药破甲深度的影响规律.利用内插值法建立了含药型罩锥角和炸高变量的双锥药型罩聚能装药静破甲深度计算公式,获得了静破甲深度随上锥角和炸高变化的三维曲面;据此,确立了双锥罩聚能装药的最佳炸高.研究结果表明,实验与数值仿真结果一致,验证了所提出的双锥罩聚能装药炸高设计方法的可行性.A design method was studied to optimize the standoff of shaped charge warhead. By experiment, the static state penetration depth of bi-conical liner shaped charge under 6.0, 6.5, 7.0, 7.5 and 8.0 times standoff and 34° and 40° cone angle were obtained. At the same time, a numerical simulation method was researched and verified on the same experiment conditions. Under different top cone angle, the change rule of the penetration depth with the change of standoff was obtained by numerical simulation. A calculation formula including the variables of cone angle and standoff for static state penetration depth of bi-conical liner shaped charge warhead was obtained. The three-dimensional surface was obtained, which indicated that the static state penetration depth varies with cone angle and standoff. Based these, the optimum standoff of hi- conical liner shaped charge warhead was obtained. simulation and the design method of standoff distance can provide reference for related research. The result of experiment and numerical of bi-conical liner shaped charge warhead
