摘要：

Based on displacement functions considering warpings caused by tensile, bending and torsion, using extended Lagrange equations, the vibration differential equations of composite wind turbine airfoil section blades were established, and solved with Galerkin method. The three kinds of airfoil section blades' free vibration characteristics were compared. The influences of composite ply angle, taper ratio and rotating speed on the free vibration charateristics of the blades were analyzed. The natural frequencies of the blades were also computed with comprehensive application of large-scale general finite element software ANSYS, Pro/E and Hypermesh. The results were compared with those of Galerkin mechod to verify the correctness of the theoretical calculations. ©, 2015, Chinese Vibration Engineering Society. All right reserved.
