为验证现有船舶动力学数值仿真模拟对船舶运动预测的准确性。以KVLCC2油轮回转运动和S175集装箱船在规则波中的摇摆运动为对象，采用控制体积法求解湍流模型封闭的非定常雷诺方程，并结合k-ω SST模型和自由面VOF方法，求解了6自由度的船舶运动动力学方程组。分析数值模拟结果发现，在不同的波浪航向角下，船舶进入规则波的回转和摇摆运动与试验数据具有良好的一致性。结果表明，现有数值方法能够满足工程目的的精度预测船舶动态参数，可作为船舶方案设计阶段操纵性预报的主要手段和重要补充。
To verify the accuracy of existing numerical simulations of ship dynamics in predicting ship motion. Taking the turning motion of KVLCC2 oil tanker and the swaying motion of S175 container ship in regular waves as objects, the control volume method was used to solve the unsteady Reynolds equation with a closed turbulence model, and the k - ω SST model and free surface VOF method were combined to solve the 6-degree-of-freedom ship motion dynamics equation system. The analysis of numerical simulation results shows that under different wave heading angles, the ship's turning and swaying movements in regular waves have good consistency with experimental data. The results indicate that existing numerical methods can accurately predict ship dynamic parameters for engineering purposes, and can serve as the main means and important supplement for maneuverability prediction in the ship design stage.
