船舶参数激励非线性运动升沉(纵摇)-横摇耦合关系的研究

A Study on Coupled Heave-roll Relation in Parametrically Excited Nonlinear Motion of Ship

本文考虑船舶参数激励非线性运动 ,导出了升沉与横摇耦合系数的计算公式 ,计算了耦合系数值 ,探讨了升沉对横摇的影响 ,进一步揭示了升沉 (纵摇 )能量向横摇运动转移的机理 ,这对于高海情下船舶运动控制具有重要意义。

The coupled coefficient formula between heave and roll is set up with considering nonlinear motion of a ship parametrically excited. The coupling coefficient values are calculated, and heave effect on roll is discussed, which further disclosed the mechanism of heave energy transferring to roll motion, and has significant value to control motion of a ship in the high seas.
