摘　　要：文中研究浅水10 MW浮式风力机的系泊布置技术及静态刚度特性,提出了一种基于刚度等效准则设计浅水浮式风力机系泊系统的方法.分别选取不同的锚链长度及配重布置方案,通过静力计算分析锚链的构型和刚度特性,分析不同配重重量和数量对于系泊线静态刚度、构型等综合回复能力的影响,并与深水母型系泊系统相关刚度参数进行比较,从而确定风力机系泊系统设计参数.结果表明:采用母型风力机系泊刚度等效的设计方法可以提高浅水系泊系统设计效率.浅水浮式风力机系泊线设计的难点在于限位能力小和张力易突变,文中提出的锚链加多个配重块的系泊线设计理念及分析方法,较好解决了浅水大功率浮式风力机系泊系统的关键问题.The mooring layout technology and static stiffness characteristics of shallow water 10MW floating wind turbine were studied, and a method to design the mooring system of shallow water floating wind turbine based on stiffness equivalence criterion was proposed. Different anchor chain lengths and counterweight arrangement schemes were selected respectively, and the configuration and stiffness characteristics of anchor chain were analyzed by static calculation, and the influence of different counterweight weights and quantities on the comprehensive resilience of mooring line such as static stiffness and configuration was analyzed. Compared with the related stiffness parameters of deep jellyfish mooring system, the design parameters of wind turbine mooring system were determined. The results show that the design efficiency of shallow water mooring system can be greatly improved by using the design method of equivalent mooring stiffness of female wind turbine. The difficulty of mooring line design of shallow water floating wind turbine lies in the small limiting capacity and the sudden change of tension. The design concept and analysis method of mooring line with anchor chain and multiple counterweight blocks proposed in this paper have solved the key problems of mooring system of high-power floating wind turbines in shallow water, and provided feasible technical approaches and analysis methods for the development of mooring system of high-power floating wind turbines in shallow water.
