摘要
针对海上风机的发展趋势,对一种混合式海上浮式风机基础的动力响应进行了研究。应用SESAM软件和FAST软件分别建立海上风机的下部浮式基础以及上部结构的数值模型,调用Aero Dyn程序包计算结构的空气动力载荷。分析系统的动态响应和基础的运动特性。改变筋腱预张力的大小,研究其对浮式基础运动响应的影响,为海上风机混合式基础的初步设计提供一定的理论依据。
In view of the development trend of offshore wind turbines, dynamic response of hybrid foundation for floating offshore wind turbines is investigated. Numerical models of floating foundation and wind turbines are built with SESAM and FAST respectively. Aerodynamic forces on the structure are calculated with AeroDyn. Motion performance of the foundation is investigated. Additionally, the effects of the pretension on the motion of the floating foundation are analyzed, which can provide theoretic basis for preliminary design of hybrid floating offshore wind turbines.
