潜艇单舱大深度破损进水模型数值分析

Numerical Analysis to Inflow Changes Model of Single-Cabin-Broken Submarine in Large Depths

本文提出一种基于平面舱壁承压能力的动力抗沉有效性判据,建立了潜艇单舱大深度破损进水模型和最大可浮深度的数值计算流程与方法,通过数值仿真计算分析了不同破口面积和潜艇升速对最大可浮深度的影响,研究表明最大可浮深度与潜艇升速具有良好的线性对应关系,并在此基础上建立了不同破口面积下潜艇最大可浮深度随升速变化的公式汇总表,为潜艇战损时指挥员的快速决策提供支持。

A criterion of the dynamic anti-sinking effectiveness is given based on the pressure-containing ability of the plane bulkhead,and the inflow changes model of single-cabin-broken submarine is established,as well as the calculating process and method of the maximum floatable depth.The influence of the broken area and the vertical speed to the maximum floatable depth is researched by numerical simulation.The results reveal that the maximum floatable depth linearly corresponds well to the vertical speed,and the summary diagram of maximum floatable depths calculating formulas to different vertical speeds is established on the basis of this regular,which can offer support to commander’s rapid decision when the submarine is broken in war.
