摘　　要：非线性大角横摇运动是危害船舶安全的重要因素,也是船舶水动力学关注的热点及难点问题。文章采用CFD方法 ,对某型驱逐舰船模在不同波长规则波中横浪航行时的横摇运动进行了数值模拟。通过与水池实验比对,数值仿真得到的稳定横摇幅值与实验值的误差在10%左右。同时,数值模拟证实了非线性横摇的两种典型特征—"多值"及"跳跃"现象。数值模拟结果表明,CFD方法可作为研究船舶非线性横摇运动的有效手段。Non-linear roll motion is a crucial factor in endangering ship＇s security and a hot issue in ship＇s hydrodynamics study. In this paper, ship＇s roll motion in different regular beam sea waves is simulated.The simulation results show good agreement with the tank test results, and the error is less than 10%. The typical phenomena of nonlinear roll-‘multi-amplitude＇ and ‘jumping＇ are also realized in the simulation.The simulation results show that CFD method can be an effective tool in studying ship＇s non-linear motion.
