摘　　要：该文采用正交优化设计方法,利用数值模拟手段,对球缺型EFP战斗部优化设计进行研究。分析了战斗部结构参数对EFP成型性能的影响规律,优化得到了口径为Φ65 mm的变壁厚球缺型EFP装药结构方案。该装药形成的EFP速度约为2.5 km/s、长径比约为3.15,对应方案的EFP外形及速度的X光试验结果与仿真计算结果吻合较好。Using orthogonal optimizing design and numerical simulation methods, EFP warhead with hemispherical liner is optimized. The effects of EFP warhead structure parameters on the performance of EFP forming is analyzed, Ф65 mm caliber EFP warhead with variational-wall-thickness hemispherical liner is optimized, The velocity of optimized EFP is about 2.5 km/s and the ratio of length versus diameter of EFP is about 3. 15. The numerical simulation shows the figure and velocity for EFP are similar to those of X ray experiments.
