摘　　要：参数横摇是第二代完整稳性五种失效模式之一,一直是船舶稳性研究的热点。通过数值计算与试验对比,验证了基于三维势流理论的KCS集装箱船规则波中运动响应模拟方法的可靠性。然后对目标船在规则波中不同初始横摇角、航速、波长和波陡情况下的横摇运动响应进行研究。结果表明:初始横摇角的大小不影响船舶发生参数横摇时的横摇幅值,但影响发生参数横摇现象的速度;随着航速的增加,横摇阻尼迅速增大,发生参数横摇的临界波陡也在增大,且随着波陡的继续增加,横摇幅值会有略微下降的趋势。Parametric rolling is one of the five failure modes of the second generation intact stability,which has been a hot topic in ship stability research.The reliability of the motion response simulation method of KCS container ship in regular waves based on three-dimensional potential flow theory is verified by numerical calculation and experiment.Then,the rolling motion response of the target ship under different initial rolling angle,speed,and wavelength wave steepness in regular wave is studied.The results show that the initial roll angle does not affect the amplitude of parametric roll,but affects the speed of parametric roll.With the increase of speed,the roll damping increases rapidly,and the critical wave steepness of parametric roll increases.With the continuous increase of wave steepness,the roll amplitude decreases slightly.
