潜艇动力抗沉非线性效应及计算分析

Evaluation of Dynamic Anti-Sink Nonlinear Effects for Submarines

  • 摘要: 应用潜艇垂直面非线性操纵性运动方程、破损舱进水方程和压载水舱排水方程,建立潜艇动力抗沉运动方程。数值计算潜艇典型隔舱破损进水后的动力抗沉运动,分析典型隔舱动力抗沉挽回运动和无法挽回运动的特征。针对不同初始航速、初始潜深和破口面积情况,数值计算得到典型隔舱动力挽回限界线。通过对典型隔舱动力挽回非线性限界线的分析,提出潜艇动力抗沉效应的概念,以及衡量潜艇动力抗沉能力大小的衡准参数——高压气吹除动力挽回深度、动力抗沉水动力初速和水动力航速系数,由此分离出潜艇动力抗沉运动中的高压气效应和水动力效应。

     

    Abstract: Based on the vertical plane nonlinear maneuverability motion equation and the damage flooding and ballast blowing equation, the submerged dynamic anti-sink equation for submarines is established. By calculating the dynamic anti-flooding motion of submarines after typical compartment damage, the nonlinear margin lines of dynamic saving moves are obtained under different initial velocity, water depth, and flooding regions. By analyzing these margin lines, 3 criterion parameters are proposed to measure the ship's sink-resistibility: the effects of high-pressure air blowing are largely determined by water depth, and the effects of hydrodynamics are based on the initial speed and speed coefficients.
