为了准确预测船舶在波浪中的运动性能，基于三维全非线性时域势流理论，研究了集装箱船在规则波浪中的升沉、纵摇和附加阻力的数值计算。采用边界元法处理四边形单元，采用一阶平板理论和四阶龙格-库塔时间积分法求解控制方程。船体由固定网格划分。考虑前向速度、静止船波、绕射波、绕射波和入射波场的非线性叠加，采用混合欧拉-拉格朗日法生成自由表面，并在边缘手动设置阻尼区域。以KCS集装箱船为例，将升沉、纵摇和波浪附加阻力的计算结果与实验值进行了比较。结果表明，该方法的最大优点是能够在短时间内得到较为准确的船舶运动预测，该方法在船舶波浪中水动力性能分析和运动预测方面具有广阔的应用前景。
In order to accurately predict the motion performance of the ship in waves, the numerical calculation of heave, pitch and added resistance of a container ship in a regular wave is studied based on the three-dimensional fully nonlinear time-domain potential flow theory. The boundary element method is used to deal with the quadrilateral elements, and the governing equations are solved by the first-order flat-plate theory and the fourth-order Runge- Kutta time integration method. The ship hull is divided by the fixed mesh. Considering the non-linear superposition of the forward velocity, the stationary ship wave, diffracted wave, diffraction wave and incident wave field, the free surface is generated by the hybrid Euler-Lagrangian method, and the damping area is set manually at the edge. Take the KCS container ship for instance, the calculation results of heave, pitch and added resistance in waves are compared with the experimental values. The results show that the biggest advantage of this method is to get a more accurate prediction of ship motion in a short time, and this method has a broad application prospect in the analysis and motion prediction of ship hydrodynamic performance in waves.
