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 character… Show more
