摘要(Abstract)：

为了获得带隔板线型聚能装药最佳的结构参数,采用正交优化设计的方法,研究了药型罩楔形角2α、壁厚δ、装药高度H、隔板宽度a、隔板楔形角2β5个因素对线型聚能射流的影响,选取L25(55)正交优化表,利用LS-DYNA软件进行仿真计算,得到了5个因素对射流最大速度和射流长度影响的主次顺序,描述了各因素对射流两个指标的影响规律,获得了最佳的结构组合a3-2β2-H5-2α4-δ4。实验证明,该装药结构对钢靶的侵彻深度大于1倍药型罩口宽,提高了线型聚能装药的切割能力。
To obtain the optimal structural parameters of linear shaped charge with wave-shaper,the method of orthogonal design was used to study five factors affect on LSC jet,including shaped charge liner wedge angle 2α,wall thicknessδ,charge height H,wave-shaper width aand wave-shaper wedge angle 2β.L25(55)orthogonal optimization table and LS-DYNA simulation software were chosen.The order of five factors impact on the jet speed and length were achieved.The influence of various factors on the two indicators of jet was described and the best combination of structure a3-2β2-H5-2α4-δ4 was obtained.The experiment showed that the maximum penetration depth of steel target was more than twice as much as mouth width of shaped charge liner,and the cutting ability of LSC was raised.
