| 摘 要： | 以大型自航抓斗挖泥船为研究对象,建立相应的水动力计算模型。主要研究抓斗挖泥作业不同阶段下船舶运动、锚泊线受力情况以及其随不同环境载荷的变化规律,为船舶安全作业提供依据。研究结果表明,船舶在抓斗旋转和卸料时最为危险,船舶横荡、横摇及各锚泊线张力受其影响很大,实际作业时应尽量保持迎浪状态,进而确保船舶作业安全。

| Abstract: | The research object of this study is an ultra-large self-propelled grab dredger. A hydrodynamic model of the ship is established for calculation. The research on dynamic response of ship and mooring lines in various operation stages and different environmental load is performed. It will be a basis for the safe operation of the ship. The results show that the ship is most dangerous during the turning and discharging operations of grab bucket. The operations have great influence on rolling, swaying motion and the tension of mooring lines. To ensure the safety of ship operation, the ship should try to be kept in head waves during actual operation. |
