Orthogonal Design of the Liner Structure in Dual-Mode Charge Warhead

  • 摘要: 针对双模战斗部小型化设计及其应用问题,利用LS-DYNA仿真软件,研究了双模战斗部药型罩结构参数(药型罩锥角、药型罩壁厚)对双模毁伤元成型性能的影响规律,揭示了各结构参数对双模毁伤元成型性能的控制规律:随着药型罩锥角和壁厚的增大,双模毁伤元的头部速度下降明显。结合正交设计方法,确定了药型罩壁厚是决定两毁伤元头部速度差的主要因素,锥角是决定各毁伤元头部速度的主要因素。得到了双模毁伤元成型性能均较佳的药型罩结构参数组合:药型罩锥角为80°,药型罩上端壁厚为5.0 mm,药型罩下端壁厚为4.0 mm,药型罩倒角弧度半径为10.0 mm。为验证模拟结果,进行了X射线成像试验,数值模拟结果与试验结果吻合较好。研究结果可为双模战斗部的进一步优化设计提供参考依据。
