摘要

摘要: 采用流体体积函数(VOF)多相流模型和动网格技术, 开展了不同长短轴比椭球头型鱼雷入水过程及水下航行的动态数值仿真研究, 分析了头型对鱼雷入水最大冲击载荷特性的影响, 建立了最大冲击载荷和入水动压及头型长短轴比之间的函数关系。仿真结果表明: 鱼雷最大冲击力与入水速度的平方成线性增加关系; 随着长短轴比的增加, 最大冲击力减小, 且其相对减小量也随之减小, 同时鱼雷在水下航行所受的阻力也会随长短轴比的增加而减小。研究结果可为鱼雷入水弹道和结构设计提供参考。

Abstract: The water entry process and underwater navigation of the ellipsoid head type torpedoes with different long-to-short axial ratio are numerically simulated with fluid volume function(VOF) multiphase flow model and dynamic mesh. The influence of head type on the maximum impact load characteristics of a torpedo during water entry process is analyzed. The functional relation of the maximum impact with the dynamic pressure of water entry and the long-to-short axial ratio of torpedo head is established. The results show that: 1) the maximum impact during water entry increases linearly with the square of the initial impact velocity; 2) with the long-to-short axial ratio of the head increasing, the maximum impact as well as its relative reduction decrease, and the resistance to the torpedo in underwater navigation also reduces. This research may offer a reference for torpedo’s water-entry trajectory and structure design.
