漂浮式螺旋叶片垂直轴风力涡轮机在复杂海洋环境下的工作性能受其动力特性的影响很大。为了更好地掌握螺旋叶片FVAWT的动态特性，本文提出了一种松弛耦合建模方法。在建模过程中，将风力涡轮机系统分为两种构型，通过叶片整体运动的传递将两种构型连接起来。通过对浮基运动和叶片变形的验证，验证了模型的可靠性。最后，对一台5 MW螺旋叶片FVAWT的动态特性进行了分析。结果表明，波浪载荷和风载荷分别影响浮体运动的幅值和平衡位置。叶片变形主要由气动频率分量决定。另外，叶片截面方位与风向的相对夹角对螺旋扭转角敏感，会导致不同截面之间气动载荷的相位差，从而导致叶片变形。该研究可为螺旋叶片式FVAWT的设计和研究提供合理的数学模型。
The working performance of floating vertical axis wind turbine (FVAWT) with helical blades under complex ocean environment is greatly influenced by its dynamic characteristics. For better grasping the dynamic characteristics of helical blade FVAWT, a slack coupled modeling method is proposed in this paper. During the modeling process, the wind turbine system is divided into two configurations, which are connected through the transmission of large overall motion of the blade. Then the reliability of the proposed model is verified by validating the motions of floating foundation and deformations of blade, respectively. Afterwards, the dynamic characteristics of a 5 MW helical blade FVAWT are analyzed. Results show that the amplitude and the equilibrium position of floater motions are influenced by wave loads and wind loads, respectively. And the blade deformation is dominated by aerodynamic frequency components. In addition, the relative angle between orientation of blade section and direction of the wind are sensitive to the helical twist angle, which will lead to the phase difference of aerodynamic loads and the blade deformations between different sections. This study could provide a reasonable mathematical model on design and investigation of the helical blade FVAWT.
