Dynamic analysis is essential before the deployment of oversized wind turbine blades. This article presents a variable-thickness blade model made of graphene-enhanced glass fiber composite material. Based on the FSDT, a model was developed using the Rayleigh-Ritz method to derive exponential polynomials that meet the cantilever boundary conditions, calculating the blade's natural frequencies and modal characteristics. Validation was performed using finite element simulation and hammer testing, ensuring the reliability of the computational method.

摘要

Dynamic analysis is essential before the deployment of oversized wind turbine blades. This article presents a variable-thickness blade model made of graphene-enhanced glass fiber composite material. Based on the FSDT, a model was developed using the Rayleigh-Ritz method to derive exponential polynomials that meet the cantilever boundary conditions, calculating the blade's natural frequencies and modal characteristics. Validation was performed using finite element simulation and hammer testing, ensuring the reliability of the computational method.
