摘要
基于Open FOAM开源代码建立船舶操纵运动仿真模块,模拟船舶在艉斜浪中的6自由度回转运动。将数值仿真结果与标模试验数据进行对比,验证了数值仿真方法的准确性。在此基础上对船舶在不同波长艉斜浪中的回转运动进行数值模拟,获得船舶回转运动轨迹及运动过程中速度和角速度的变化,分析艉斜浪参数对船舶回转性能和机动性能的影响。
A solver is developed based on open-source code OpenFOAM to simulate the 6-DOF turning circle maneuver of a ship in quartering sea.Firstly,the numerical simulation results are compared with the tank test results to validate the numerical simulation method.Then numerical simulations were carried out on the turning circle maneuver in quartering sea with various wavelengths,and the ship's turning circle maneuver trajectories and the corresponding velocity and angular velocity in the process were obtained.The influence of wave parameters on the maneuverability of the ship in the quartering sea is studied.
