| 摘 要： | 采用六自由度舰船操纵性方程与横摇波浪力矩耦合构成动力学模型,对舰船在规则波浪中的操纵与横摇耦合运动特性进行了模拟研究.其中操纵性方程采用MMG模型,波浪力矩由切片法计算,舰船航向按PD控制.模拟计算了某船正横规则波浪下保持航向的横摇运动,计算结果与单自由度理论结果进行了比较,其幅频曲线与相频曲线两者符合较好,间接证明了耦合构成动力学模型的有效性.在此基础上计算了不同浪向角和航速下的横摇运动,以横摇等值极坐标曲线表征舰船规则波浪中的横摇特性,从而给出了规则波浪下舰船耦合动力学所描述的运动特征.

| Abstract: | By uniting maneuvering motion equations of six-freedom degrees and rolling moment of a ship in regular waves,the thesis constructs ship dynamic model,in which MMG model in calm water is adopted and rolling moment is calculated with STF method,and proportional & differential control model is used for keeping course.Based on the above model,this paper simulates rolling motion of a ship keeping course in regular waves.The results of simulation,compared with the theory results of single freedom degree,is very c... |
