【摘要】 随着日益强烈的节能减排需求,在船舶运动控制系统设计时,引入了波浪增阻对船舶航行性能和控制质量影响的研究.文中根据势流理论对船舶横摇运动波浪增阻进行分析,给出了模型解析表达式.利用水动力计算软件ANSYS-AQWA对船舶横摇运动产生的波浪增阻进行计算.通过回归分析确定了模型中的未知参数,验证了模型的可行性.基于该数学模型,分析了船舶横摇运动姿态与波浪增阻的具体时域关系,为航速损失最小的船舶减摇控制策略研究提供理论依据.更多还原

【Abstract】 With the increasing needs of energy saving and emission reduction,the effects of added resistance on ship navigation performance and the control quality have attracted considerable research interests.The added resistance of ship roll is analyzed based on the potential flow theory,and an added resistance model is presented.The added resistance induced by ship roll is calculated with the hydrodynamic computation software ANSYS-AQWA.The rolling added resistance model is modified with regression analysis,and feasibility of model validated.The relationship between roll attitude and added resistance in the time domain is analyzed based on this model.The results provide a theoretical foundation for controlling ships’ anti-roll capability with minimum speed loss.更多还原
