基于经典 MMG 模型建立操纵性和横摇四自由度耦合模型,并利用耦合模型叠加波浪力的方式,论文对一艘 S175自航船模进行波浪中操纵性和横摇预报,并根据自航模试验进行对比验证;其波浪力采用三维面元法计算,并根据船舶实时速度和遭遇浪向进行二维插值。在验证模型准确性后,对船舶在不同舵速、浪向角下的操纵运动进行时域模拟,比较了舵速和遭遇浪向对船舶舵效的影响,分析了浪向、波频对船舶操纵和回转时横摇的影响。

A coupling 4-DOF model of maneuvering and rolling was established based on MMG model. The model was applied to prediction of turning and rolling motions for a S175 free-running ship model in waves and validated with free-running model test. Wave force was calculated through 3D panel method and interpolated by both ship instant speed and wave encounter angle. Time-domain simulations of maneuvering were conducted in different rudder speeds and encounter wave angles. The influence of encounter wave angle and wave frequency on ship maneuvering and roll motion in turning circle was discussed.
