摘要
随着节能减排需求的日益强烈,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。该文根据势流理论对船舶横摇运动姿态的波浪增阻进行分析,并给出了解析表达式。利用水动力计算软件AQWA对船舶横摇运动产生的波浪增阻进行计算。通过回归分析方法对AQWA软件仿真得到的数据进行处理,确定模型中的未知参数。将模型计算结果与AQWA仿真数据对比,验证了该种模型分析方法的可行性。研究成果可为航速损失最小的船舶减摇控制策略研究提供理论依据。
With the increasing needs of fuel-efficiency and emission reduction, the research of added resistance＇s effect on the ship navigation performance and control quality should be considered, when a ship motion control system is designed. The added resistance due to ship roll motion is analyzed based on potential flow theory and an added resistance model is presented based on the analysis. The roll motion added resistance is computed with hydrodynamic calculation software AQWA. The added resistance model is modified with the data from AQWA by a regression analysis method. The feasibility of model is validated by comparing the AQWA simulation results with the calculations of the added resistance model. Results provide a theoretical foundation for the study on the control strategy of ship anti-roll under the condition of minimum speed loss.
