摘要: 基于三维势流理论,研究了船舶纵荡、横荡、垂荡、横摇、纵摇和艏摇等六自由度幅值响应算子受船舶与码头间距(5 ~ 500 m)、码头类型(方形码头及圆筒形码头)的影响规律;分析了完全时域耦合系泊状态下,船舶纵荡、横荡、垂荡、横摇、纵摇和艏摇等六自由度运动响应幅值随着时间历程变化规律。结果表明:船舶频域内六自由度的幅值响应算子不受船舶与码头间距的影响;不同的码头形状对船舶的时域运动影响不同,方形码头对船舶的纵摇、艏摇和横荡等三自由度的影响较为剧烈,圆筒形码头对船舶横摇、纵荡和垂荡的影响更为显著。研究结果可为同类船舶停靠码头进行系泊时提供一定的参考和技术指导。

Abstract: Based on the three-dimensional potential flow theory, the effects of ship-to-wharf spacing (5 to 500 m) and wharf types (square wharf and cylindrical wharf) on 6-DOF response amplitude operators (RAO), including surge, sway, heave, roll, pitch and yaw, were studied. In the case of coupled mooring in full-time domain, the variation of the response amplitude of the ships 6-DOF (pitch, sway, heave, roll, pitch and yaw) changing with time history was analyzed. The result shows that the 6-DOF response amplitude operators in ship frequency domain are basically not affected by the distance between ship and wharf; and different wharf shapes have different influences on the ship motions, that is the influence of square wharf on ships pitch, yaw and roll is more severe, while the influence of cylindrical wharf on ships roll, pitch and heave is more significant. The research results can provide some reference and technical guidance for mooring of similar ships.
