码头系泊缆绳张力的计算

系泊船舶用根缆绳系泊在码头上，缆绳张力的模型实验研究和理论计算对于缆绳的选娶，系泊设备的设计，系泊方式及预紧力的确定，以及船级社规范的制订都有着重要的指导意义。国内对码头系泊的研究相对较少，且主要依赖于模型实验，本文对系泊船舶缆绳张力的计算建立了数学模型。用蒙特卡洛算法对系泊非线性方程组进行了求解，并编制了计算程序，与实验结果相比，有较好的一致性，用此数学模型的方法求解船舶在风、浪、流联合作用下缆绳的静张力是可行的。

Analysis of Mooring Lines Forces of a Berthed Ship

Ships are moored to the shore structures with a number of moorings.The determination of the tension forces in them is essential for the design of moorings and for berthing structures.This paper is intended to derive the equations of static equilibrium for the mooring lines when the ship is subjected to surface wind,current and restricted waves.The computal results are compared with the ones obtained from the experiment conducted on a 50kDWT bulk carrier model and they are found to be in good agreement.The present theoretical investigations will enable the designer to evolve efficient mooring systems.
