Blade Model

Wind turbine blade model is analyzed based on finite element method. Research and comparison of blade natural frequencies is made in different rotational working conditions taking into account external factors such as the rotational inertia force. Also the relationship between the composite ply angle and natural frequency is analyzed. The result shows that the nature frequency of wind turbine blade is influence greatly by the stress stiffening effect for the blade rotation. And the nature frequency of wind turbine blade can be designed by adjusting the single fiber layer ply angle of blade.

Blade Model

Dynamic stress of wind turbine blade has great influence on its reliability and fatigue life. In order to decrease the magnitude of dynamic stress, frequency modulation method is often used to avoid resonance. This paper created composite material model for a wind turbine blade. Blade model was imported to abaqus environment for modal analysis. In view of the characteristics of fiber reinforces plastic, a mesh was built to carry out the model analysis, and the first 6 orders of the vibration frequencies and mode shapes were obtained, by imposing certain bound on the root of blade. Meanwhile, The analysis results of the composite material blade considering stiffening effect were obtained. This method can shorten modeling time and improve working efficiency, and also it is the base for blade structure calculation and check and new product developing.
