A Brief Analysis of Mooring System Based on Static Analysis

摘要: 系泊系统分析是通过获取系泊系统的自身参数以及周围环境参数，对系泊系统的钢桶和各节钢管的倾斜角度、浮标的吃水深度、和游动区域进行求解，从而判断系泊系统的工作状态。首先，通过对系泊系统整体和各部件的力学分析建立模型，并引入悬链线方程求解锚链方程，运用递推方程求解未知参数。其次，将数学建模题目中已知参数代入，利用穷举法求解临界风速，判断系统运动状态，在不同情况下分别运用MATLAB编程求解。最后，利用穷举法求出重物球重量变化范围。从而实现系泊系统状态的判断与分析。

Abstract: Through the mooring system’s own parameters and the surrounding environment parameters, mooring system analysis is to solve steel drums and sections of the steel pipe tilt angle, buoy of the draft depth, and swimming area of the mooring system, which determine the working state of the mooring system. Firstly, the model is established by static analysis of the mooring system and the components, and the catenary line equation is introduced to solve the equation of anchor chain, recurring equations to solve the unknown parameters. Secondly, we substitute the known parameters of subject into the equation, and use the exhaustive method to solve the critical wind speed and to determine the state of motion of the system. In different circumstances, we respectively use MATLAB to solve the equation. Finally, the range of heavy weight is determined by exhaustive method so as to realize the state judgment and analysis of mooring system.
