| Abstract: | in this paper, theory of excitation vibration is reformed, calculated for of wind turbine blade from the numerical analysis, and self-excited vibration of blade is analyzed on operation of wind turbine. By improving analysis method of excitation vibration theory, analyzing synthetically mechanism of wind turbine blade vibration, the root cause of the wind turbine blade vibration is got and criterion of blade stability is put forward. By compared the calculation result and the actual run condition of wind turbine, the method is good reliability and practicability. |
| Keywords: | excitation theory wind turbine blade unsteady flow stability |
