为了研究波浪高度、波浪周期和谱峰因子对拖航方式下漂浮式风机水动力特性的影响，基于势流理论的数值计算分析方法，使用SESAM软件中的时域耦合分析工具RIFLEX模块对新型漂浮式结构的拖航过程进行数值模拟，通过改变环境参数得到结构在不同工况下六自由度上的运动响应和拖缆绳内力值变化情况。计算结果表明，随着波浪高度和波浪周期的增加，新型漂浮式风机运动响应和拖缆力也随之增加，而谱峰因子的改变对结构的水动力特性影响较小。研究成果可为大容量风电机组浮式平台结构的拖航过程提供一定参考。
To investigate the effects of wave height, wave period, and spectral peak factor on the hydrodynamic characteristics of a floating wind turbine during towing operations, a numerical analysis method based on potential flow theory was employed. this study employed a numerical computational method based on potential flow theory. Using the RIFLEX module (a time-domain coupled analysis tool) in SESAM software.RIFLEXBy varying environmental parameters, the six-degree-of-freedom motion responses and mooring line forces under different operating conditions were obtained. The results indicated that wave height and wave period significantly influence the motion responses of the floating offshore wind turbine system and the dynamic tensions in mooring lines. Specifically, both the motion responses and towing cable forces increased with higher wave heights and longer wave periods, while the spectral peak factor exhibited a comparatively minor influence on the hydrodynamic behavior. The research findings can provide valuable references for the towing process of large-capacity floating wind turbine platform structures.
