The paper have described the vibration and damping analysis of carbon fiber wind turbine blade with viscoelastic treatment using commercial ANSYS program. system including a layer was attached on inside layer. Firstly, natural frequencies mode shape pure were compared treated modal analysis. There 1mm, 2mm, 3mm thickness finite element model to be constructed. results show little changes in lower first but getting smaller higher modes. Finally, frequency response functions damped undamped calculated for investigating effect As shown results, has good control blade.
