| 摘 要： | 基于力的平衡关系建立了系泊船舶在风和潮流作用下缆绳张力和运动的计算模型(Qmoor),其中根据船舶类型和吨位确定其水下的迎流面积和水上的迎风面积,由经验性公式计算风、流对码头前船舶的作用力,缆绳张力采用考虑缆绳非线性变形的Wilson公式计算,同时也考虑了护舷的变位与靠泊力之间的非线性关系。计算结果与物理模型试验结果较一致,且与Optimoor软件的计算结果进行了对比。

| Abstract: | A software （Qmoor） for calculating mooring line forces and movements of a moored ship under combined action of wind and current was presented based on static force equilibrium principle. The upstream face area above water and underwater windward area were determined on the basis of ship type and tonnage.The wind and current load was calculated by experimental formula. The non-linear effect of mooring lines and fenders was also taken into account. The computed results and the experiment data are in good agreement.Meanwhile, the results are compared with Optimoor results. |
