Aerodynamic Design and Modal Analysis on Wind Turbine Blade Based on CAD/CAE

Abstract:

Wind turbine blade is an important component to capture wind energy and converse energy. Basing on Wilson optimization method and engineering pratice, 2MW wind turbine blade’s aerodynamic profile is designed. Meanwhile, in order to avoid the resonance damage, top 10 rank modal frequencies and displacement gradient distribution contours are obtained through modal analysis. The results show that blade’s natural frequency does not coincide with the external excitation frequency, which avoids the resonance damage. Blade’s major vibration forms are waving and shimmy, requiring the ability of excellent resisting torsion. Therefore, the design should enhance bending stiffness of the blade. This paper provides an effective method for large wind turbine blades’ design and optimization.
