Theories and Experiments of Torpedo Shaped Charge Warhead Penetration Into Water-partitioned Armor

  • 摘要: 为了合理预测鱼雷聚能战斗部对含水复合装甲的侵彻威力, 基于A-T模型和两阶段孔径增长理论, 并结合基于虚拟原点理论的侵彻体侵彻过程分析, 提出了对含水复合装甲侵彻深度和穿孔直径的理论模型, 其中侵彻体断裂模型由郑哲敏提出的断裂时间公式描述。开展了缩比鱼雷聚能战斗部侵彻含水复合装甲试验研究, 其中鱼雷头段分别采用单层铝板和累计一定厚度的间隔铝板模拟, 同步开展侵彻威力数值仿真。理论计算中, 聚能侵彻体成型参数通过数值仿真获取并作为输入, 对理论计算、仿真和试验结果进行了对比分析, 验证了理论模型的合理性。理论计算可快速输出计算结果, 相关研究可以为鱼雷聚能战斗部威力快速预测、优化设计以及针对潜艇防护结构尺寸及参数特性的大威力新型聚能战斗部技术研究提供支撑。
