系泊系统对于船舶及海上浮式结构物的定位十分重要。钢质系泊缆索是业界广泛采用的一种形式。由于其提供的恢复力与浮体位移之间呈现非线性关系,故针对此种系泊方式基于Taylor展开方法得到了非线性的刚度系数及相应的系泊刚度矩阵,研究了其在系泊定位及水动力计算方面的应用。分析表明该方法可以较为方便地计及刚度非线性的影响。
Mooring systems are important for the positioning of ships and offshore structures. Steel mooring lines are a widely used form of the industry. Because of the non-linear relationship between the restoring force and the displacement of the floating body, the nonlinear stiffness coefficient and the corresponding mooring stiffness matrix are obtained based on the Taylor expansion method for this mooring method. Application of hydrodynamic calculation. Analysis shows that this method can more easily take into account the impact of stiffness nonlinearity.
