船舶在随浪中的运动与横甩预报

The prediction of motion and broaching-to of a ship in following seas

本文在水平的随船坐标系下 ,建立了船舶在波浪中的六自由度操纵运动方程。进行船舶在波浪中的回转运动和 Z形操纵运动模型试验 ,验证数学模型的正确性。通过不同波浪和航速条件下船舶 Z形操纵运动的模拟计算 ,预报船舶在随浪中的横甩 ,预报结果与试验结果比较一致。

This paper describes the six degree maneuvering motion equations of a ship in waves based on the horizontal ship fixed coordinate system. The ship model tests were carried out to verify the mathematical model above. The occurrence of broaching to in following seas was predicted by means of zigzag maneuver simulations. A comparison between the simulations and the experimental results shows a good agreement.
