摘要：In this paper, a 3D source distribution technique is used to calculate the coupled motions between two ships which advance in the wave with the same speed. The numerical results of coupled motions for a frigate and a supply ship have a good agreement with the experimental results. Based on the 3D coupled motions of two ships, a spectral analysis is employed to clearly observe the effect of speed, clearance and wave heading on the significant relative motion amplitude (SRMA) of two ships. The method presented in this paper will be helpful to select suitable clearance, speed and wave heading for underway replenishment at sea(RAS).

摘要：本文依据切片理论计算了某细长船加装减摇组合附体后的运动响应 ,给出了舰船加装组合附体后的水动力系数变化的表达式。将半潜体的贡献分成两部分 ,一部分为与来流攻角和速度有关的粘性升力 ;一部分为与剖面横向绕流速度的平方成正比的粘性横向阻力。考虑到固壁面影响 ,修正首鳍的展弦比 ,将鳍上产生的升力加入到船的运动方程中。同时将试验值与计算值进行了比较 ,从比较结果来看 ,本文提出的方法作为工程应用中方案初步设计。
