摘　　要：基于MMG思想建立了考虑风、波浪和海流作用下船舶漂移运动数学模型,给出了数值求解方法。以某无动力拖网渔船为例,计算预报了其海上漂移运动轨迹,并与实船试验结果进行了对比。结果表明模型预报轨迹与渔船海上试验实际漂移运动轨迹吻合良好,说明文中建立的船舶漂移运动模型可靠有效。The drift motion mathematical model of ship is established based on MMG(Mathematical Modeling Group)method under the action of wind,wave and surface current.And its numerical calculation method is presented.An example of the drift motion model application for unpowered trawler is illustrated.In the procedure,the drifter-trawler trajectories are calculated,and compared with test result.The result shows that the model predictions are in agreement with full scale experiment results.It illustrates that the presented models can provide reliable ship drift trajectory for search and rescue.
