码头系泊船舶缆绳张力的混沌解法

摘要

Mooring lines tension determination is of significant importance for mooring design and berthing structures.This paper firstly presents numerical method calculating mooring lines' static force of vessel subject to wind,current and wave.Then COA method is employed to solve the mooring equations by transferring them into an optimization problem.The computed results and the experiment results are in satisfactory agreement by comparison with each other.%码头系泊船舶缆绳张力的理论计算对于缆绳的选取、系泊设备的设计、系泊方式、缆绳预紧力的确定，以及船级社规范的制订都有着重要的指导意义.文中对小波浪水域码头系泊船舶缆绳张力的计算建立了数学模型，引入混沌优化的方法对非线性系泊方程组进行了求解，其结果与实验结果对比有较好的一致性.
