本文利用受力平衡分析,建立了微分方程模型,利用MATLAB对假设的锚链曲线方程进行计算并绘制其曲线图形,构造二次曲线拟合,借鉴二分法逼近的思想求解锚链与钢桶连接处的坐标并对锚链与钢桶连接处的坐标点求导,从而确定钢桶倾角。给出了海水静止状态下风速为12 m/s时的系泊系统设计,并且考虑了风力和水流力同时存在的情况,给出了它们在同向和垂直这两种极端情况下的系泊系统设计。
In this paper, differential equilibrium model is established by using force balance analysis, the imaginary chain curve equation is calculated and plotted by MATLAB, the conic curve fitting is constructed, and the connection of anchor chain and steel barrel At the coordinates of the anchor and the connection point of the bucket at the guidance point, so as to determine the drum angle. The mooring system design is given when the wind speed is 12 m / s at sea quiescent state, and the coexistence of wind power and water flow is taken into account. The moorings at the same extreme and vertical extreme conditions are given system design.
