| Abstract: | The impact on the operation of wind turbine blade by self-excited vibration is analyzed through the theoreti- cal calculation during the structure design of wind turbine blades. The primary reason inducing the wind turbine blade vibration is founded with the application of the vibration theory combined with the wind turbine blade vibration mecha- nism, and the corresponding criterion is proposed. Finally it is concluded that the primary reason which influence the stability of blade vibration is the inflow velocity of air and the sine value of the blade chord angle. |
