针对串联战斗部前级装药兼顾侵深与开孔的要求，采用正交试验的极差分析方法，结合射流成型及侵彻钢靶的数值仿真结果，分析药型罩结构参数对于杆式射流侵彻性能指标影响的主次顺序，发现当相对壁厚值为3.4%时，侵彻深度达到最大。找到了一定侵彻深度条件下（1.7D），开孔能力最佳的等壁厚球缺罩结构参数的最佳组合（h= 0.045D，r1 = 0.579D）。简单提出了等壁厚球缺罩的设计方法，并进行了侵彻钢靶的静爆试验。数值模拟结果与试验结果吻合较好。研究结果为聚能装药技术的进一步研究提供了参考依据。

According to the requirement of penetration depth and hole of tandem war-head precursor charge, influence of the charge structural parameters of liner on formation of the shaped jet was studied by orthogonal design test and extreme analysis. And it is found that at the relative thickness of 3.4% the maximum penetration depth was reached. The optimal combination of hemispherical charge structural parameters (h=0.045D, r1=0.579D) under fixed penetration depth (1.7D) with biggest hole diameter (0.42D) was obtained. A simple algorithm was presented for the hemispherical liner charge design of structures. Through the exploding experiment of shaped charge jet penetrating steel target, the simulation results are in good agreement with the experimental results, which provides a reference for the further study of shaped charge technique.
