| 摘 要： | 采用时域数值模型,对横浪作用下码头前系泊船舶的运动响应进行了研究,分析了波高、周期、水深、船舶尺度及码头型式等因素对撞击速度的影响.结果表明:当波浪周期小于般舶自振周期时,撞击速度随波高的增加线性增长;波浪周期越大,撞击速度越大;船舶装载度(吃水)越小,撞击速度越大;墩式码头(无限开敞水域)中系泊船舶的撞击速度大于岸壁...

| Abstract: | Motion responses of a moored ship under the action of beam seas were calculated using a time-domain numerical model.Correlations among wave height,period,water depth,ship size,wharf type and impact velocity were tested.It is shown that the impact velocity increases linearly with wave height when the wave period is less than the natural period of a ship.And it increases with the increasing wave period,while decreases with the increasing ship draft.It is higher in breasting dolphin(infinite domain) than in bu... |
