基于悬链线理论的系泊系统的应用

Application of Mooring System Based on Catenary Theory

通过对浅海系泊系统整体结构进行受力分析,建立锚链、刚体及浮标受力平衡方程,结合悬链线理论,构建锚泊动力系统算法。对不同风力下系泊系统的吃水深度、浮标游动半径、重物球重量、刚体倾斜角、锚链悬浮高度和水平距离进行求解,并利用MATLAB拟合出锚链形状图,保证结构物和系泊系统的安全。所得结果可为单点系泊、类似系统研究和近浅海观测网运作提供一定的参考。

Through the force analysis of the overall structure of the shallow sea mooring system,we establish force equation of anchor chains,rigid bodies and buoys.And it is combined with catenary theory.Then we construct catenary mooring system algorithms to calculate the draught of the mooring system under different wind and sea water resistance,the swimming radius of the buoy,the weight of the weight ball,anchor chain suspension height,horizontal distance and the shape of the anchor chain.Lastly,we use MATLAB to fit the shape of the anchor chain.The outcome can ensure the safety of the structure and the mooring system.The results show that it can provide certain reference and help for single-point mooring,research on similar systems and operation of offshore observation networks.
