Dynamic Analysis of Wind Turbine Blades UsingRadial Basis Functions

[摘要] Wind turbine blades play important roles in wind energy generation. The dynamic problems associated withwind turbine blades are formulated using radial basis functions. The radial basis function procedure is used to transform partial differentialequations, which represent the dynamic behavior of wind turbine blades, into a discrete eigenvalue problem. Numerical results demonstrate thatrotational speed significantly impacts the first frequency of a wind turbine blade. Moreover, the pitch angle does not markedly affect wind turbineblade frequencies. This work examines the radial basis functions for dynamic problems of wind turbine blade.
