系泊船舶试验中风荷载的模拟

基于大型LNG船舶系泊物理模型试验，对2种试验室风荷载模拟实现技术（风机法与挂重法）进行分析与对 比。由风压力试验结果得出“风机法模拟风荷载结果与多个常用经验公式计算结果相差不大”的结论。风浪联合作用下的 船舶系泊模型试验结果表明:单纯风工况下2种方法测得的系缆力有所差异，但叠加波浪荷载后这种差异变小且不同位置缆绳 受力分配状况也有所改善。对上述结论及其形成原因进行与探讨，为船舶系泊物理模型试验中风荷载的合理模拟提供借鉴。

Wind load simulation in physical model experiment of ship mooring

In the studies of ship mooring physical model experiment, two wind loads simulation methods, Fan-method and Hanging Weight-method, are discussed. The result of the wind force experiment shows that the Fan-method is consistent with the other three empirical formulas. The testing result of the ship mooring experiment with the wind force only shows that the mooring forces have some differences between the two wind loads simulation methods, but the difference is reduced with the stack wave load, and the force distribution condition of the mooring lines is improved. The above conclusions and reasons are discussed, which may serve as reference for the reasonable simulation of wind loads in physical model experiment of ship mooring.
