使用ANSYS有限元软件研究在风荷载作用下垂直轴风力发电机组(Vertical-axis wind turbine,VAWT)主轴在旋转状态下的风致动力疲劳问题.首先,在频域内,研究在脉动风作用下机组旋转主轴(转速为15.5 m/s)三个关键位置处的风动力响应特性.然后,基于机组旋转主轴风动力响应的计算与分析,对机组旋转主轴进行风致动力疲劳分析,计算其疲劳寿命耗用系数,以评价该机组旋转主轴的工作状况.

The wind-induced dynamic fatigue of the main-shaft in a vertical-axis wind turbine(VAWT) under rota- tion was studied with ANSYS code. Firstly, the dynamic responses for three critical positions of the main-shaft in the verti- cal-axis wind turbine were analyzed taking rotation and wind loads into consideration. Based on the investigation of the dy- namic responses, the wind-induced dynamic fatigue of the main-shaft was then studied, so as to determine the fatigue life usage coefficient and evaluate the working requirements of the main-shaft in the VAWT.
