摘要

摘要: 水下阵列爆炸威力场体积计算方法研究有助于提高舰艇水下防御能力。为了简单准确地计算出三维模型水下阵列爆炸威力场的体积大小, 文中利用AUTODYN软件中将一维结果映射至三维模型的功能, 提出一种快速估算仿真结果的方法, 将水下爆炸威力场边界拟合成圆, 近似成阵列球体进行研究, 减少了仿真计算量。通过与SolidWorks建模所得数据对比可知, 文中方法可通过威力场横截图形的径向尺寸估算三维模型水下爆炸威力场的大小, 并得出结论: 同一时刻的水下爆炸冲击波形成的威力场基本不受冲击波相互作用的影响。文中研究可为简化水下阵列仿真计算以及舰艇有效防御鱼雷攻击提供参考。

Abstract: To calculate the volume of underwater explosive power field of three-dimensional model simply and accurately, this paper proposes a calculation method for quickly estimating simulation results based on the function of AUTODYN software that the one-dimensional results can be mapped to three-dimensional models. In this method, the underwater explosive power field boundary is synthesized into a circle, which approximates an array sphere, and the computational cost is reduced. Compared with the data from SolidWorks modeling, it is concluded that this method can estimate the size of underwater explosion power field of the three-dimensional model according to the radial dimension of cross section of the power field, and the power field formed by the underwater explosion shock waves at the same time is not affected by the shock wave interaction. This research may provide reference for simplifying simulation calculation of underwater array and effectively defending warship against torpedo attack.
