摘要(Abstract)：
为获得椭圆形罩线型聚能装药较优的结构参数组合,运用正交设计方法对影响射流成型的主要结构参数进行优化设计,获得了不同的试验方案。利用ANSYS/LS-DYNA对各方案进行了数值模拟,得到了不同方案的最大射流速度和射流断裂前的最大长度,经对数值模拟结果分析获得了最佳的参数组合方案。各因素对射流速度和射流长度的影响规律由主至次分别为n→δ→a和n→a→δ,较优参数组合方案分别为n1-δ3-a1和n3-δ1-a1。
The different projects of main structure parameters of the linear shaped charge(LSC)with oval cover were designed by the orthogonal optimization method.To obtain better main structure parameters of the LSC,all of the projects were simulated numerically with ANSYS/LS-DYNA program.The most jet velocity and pre-breakup jet length of the different projects were obtained.The optimal projects were achieved by analysis of the simulation results,and the results indicated that various factors influenced rules of jet velocity and jet length from primary to subordination were n→δ→aand n→a→δrespectively,and the best projects were n1-δ3-a1 and n3-δ1-a1 respectively.
