[Abstract] The hub is an important part of wind turbine. Its structure and deflection are plex,
which is very difficult to get the precise results of stress of the hub using traditional
mechanical technique. The static intensity analysis of the hubs of and wind
turbine has been plished using the ANSYS software. In the process of designing the
hubs of and wind turbine, the technology of alterative section structure has
been introduced essfully which result in the reduction of weight, improving availability
of the material, lowering the difficulty of manufacture and the cost.
