Paper Title:
Large Wind Turbine Blade Layer Design and Dynamics Characteristics Analysis
  Abstract

A 2.5MW wind turbine blade is modeled. The maximum static stress obtaining by the finite element method is compared with the theoretical analysis’s. The results acquired by both of them are same with each other, which validate the rationality of the finite element computational modeling. We find out the weakness regions of the blade by modal analysis on blade. This parper studies the effects of the axial of the fibrous layer, the proportion of axial fiber and the number of layers on the blade dynamic characteristic, respectively, and designs an optimization scheme to improve the blade dynamic characteristic. The research shows that adopting multiaxial, the rational fiber layers' proportion and increasing the layer number can be used to enhance the blade strength; the optimization scheme of the blade layer design in this way can improve the blade dynamic characteristic effectively and apparently.
