| Abstract: | In order to improve aerodynamic and structural performance of wind turbine baldes, the flapwise and edgewise vi-bration mode of blades is obtained based on aerodynamic and dynamic structural model of wind turbine rotor.The coupling aeroelastic model including displacement and vibration is presented through choosing the basic degrees of freedom correspond-ing to elastic structural model.The optimization model of wind turbine blades is presented based on the output power and com-ponent of wind turbine rotor.With the model presented in this paper, one 5MW wind turbine rotor is applied and optimized. The output powers, axial and tangential forces of original and optimized blades are simulated and compared to validate the reli-ability of the design method. |
