Simulation Analysis of Guided Wave Testing on Wind Turbine Blade Shell with Epoxy Resin and Semi-Analytical Finite Element Modeling
Abstract:
Non destructive testing is very important on wind turbine blade since wind energy has been an upgrowing industry as green energy.For the linetype of blade is twisty ,it can not be described easily in Cartesian orthonormal coordinate.A special twisty coordinate system is proposed.The wave dispersion curve of blade shell is calculated by semi-analytical finite element method and dynamical simulation of wave propagation on blade is finished.Both results agree well,showing the validity of guided wave testing on wind turbine blade.
