漂浮式风机系统的风机和浮式基础由不同单位研制，设计过程需要考虑数据传递问题，针对该问题以10 MW漂浮式风机的OOstar基础为研究对象，建立全耦合、限制性强耦合及限制性弱耦合3种模型，用不同计算模型进行时域模拟及频谱分析，探究不同耦合方法导致浮式风机系统动力响应的差异。结果表明，与限制性弱耦合相比，限制性强耦合的计算结果更接近全耦合计算结果；对比限制性强耦合与全耦合计算结果，纵荡差异在10%以内，垂荡差异在5%以内，纵摇差异在2%以内，1号缆系缆力差异在5%以内；对于关键响应参数，限制性强耦合结果稍大于全耦合结果，因此采用风机厂家提供的全耦合塔顶载荷作为输入数据进行浮式基础设计能够获得较可靠的结果。
The wind turbine and floating platform of the floating wind turbine system are developed by different units. The data transmission problem needs to be considered in the design process. Aiming at this problem, the 10 MW floating wind turbine and the OOstar platform of the response are taken as the research object. Three models of full coupling, restricted strong coupling and restricted weak coupling are established. Time domain simulation and spectrum analysis are carried out with different calculation models to explore the difference of dynamic response of floating wind turbine system caused by different coupling algorithms. The results show that compared with the restricted weak coupling, the calculation results of the restricted strong coupling are closer to the full coupling calculation results. By comparing the results of restricted strong coupling and full coupling, the difference of surge is less than 10 %, the difference of heave is less than 5 %, the difference of pitch is less than 2 %, and the difference of cable force of No.1 cable is less than 5 %. For the key response parameters, the restricted strong coupling results are slightly larger than the full coupling results. Therefore, the full coupling tower top load provided by the fan manufacturer is used as the input data for the floating platform design to obtain more reliable results.
