不同航态下船舶运动规律仿真研究

The simulation studies on a ship's movement pattern under the various sailing situations

主要根据波浪叠加理论,采用ITTC单参数标准海浪谱对随机海浪作用下船舶线性横摇、纵摇运动进行建模和仿真研究,探讨不同船型、各种航态(不同海况、不同航速、不同航向)下船舶横摇和纵摇运动规律,为进一步研究船舶的减摇预报与控制打下基础。

This article applies ITTC single-parameter ocean wave spectrum to simulate the linear rolling and pitching movements of ships under random ocean waves according to superposition theory. It mainly discusses the movement of different ship types and various sailing situations, including ship direction, ship speed, and sea conditions on the ships＇ rolling and pitching movement pattern to build a good basis for bringing the studies of anti-rolling control and prediction to the next step.
