潜艇动力抗沉非线性效应及计算分析

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。

Evaluation of Dynamic Anti-Sink Nonlinear Effects for Submarines

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 nonlin- ear 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.
