摘要
本文对多艘船舶在平行运动于限制航道中的船体间水动干扰力、力矩进行了理论计算。由细长体渐近展开匹配方法,建立了时间关系的积分方程式。采用离散化模型,沿各船体纵轴分布源(汇)点及旋涡点,并在船后尾流区分布旋涡点以计入“记忆效应”。本文根据离散化模型,计及奇点间的相互干扰作用,提出了纵向流体干扰力计算式及横向流体干扰力附加项。理论计算与拘束模试验符合良好。
The hydrodynamic interaction between ships moving parallel in constr-ained waters are calculated.By using matched asymptotic expansions thetime-dependent integral equations are set up.Adopting discrete procedurethe sources and vortices are distributed along the ship axis and the vorticeswhich represent the memory effect are distributed in the wake field.Applying discrete model,the calculation formula of longitudinal hydr-odynamic interaction force and additional terms of lateral hydrodynamicInteraction forces are obtained.The theoretical calculations are in accorda-nce with captive model tests.
