摘要
针对预测船舶在波浪中的运动情况这一问题进行研究。首先,研究大型船舶在波浪中的运动特点,描述了船舶在水中的运动坐标系,并分析船舶在2种坐标系下的多种运动;然后,在此基础上对船舶运动的数学模型进行研究;对于船舶的动态预测,研究基于卡尔曼滤波理论进行预测的算法。最后,针对给定的某型船只的具体参数,在给定海情下进行船舶动态预测仿真,并对仿真结果进行分析。通过预测仿真实现,能够更好地预知船舶在波浪中的动态,及时调整船舶姿态,有效保证船舶安全运行。
In this paper,we study the problem of predicting the ship motion in waves. Firstly,the motion characteristics of large ships in waves are researched,and the coordinate systems of ship movement in the water are described. At the same time,many kinds of movement are analyzed in the two coordinate systems. Then,the mathematical model of ship motion is studied. In order to predict the condition of ship in waves,we adopted the Kalman filter. Finally,on the given sea conditions,the prediction of ship movement are simulated and analyzed. Through the simulation,we can predict the ship movement in the waves accurately,and adjust the ship posture timely,guarantee the ships safe effectively.
