Finite Element Analysis of Tube Tower for Vertical Axis Wind Turbine

It is very significant for the vertical axis wind turbine to design the best support structure with high strength and stiffness. This paper discusses modeling a kind of tube tower structure of the vertical axis wind turbine and carries out static and modal analysis based on the finite element method. The static and modal characteristic of tube tower such as stress, strain and mode shapes are obtained accurately which can provide basis to optimal design the support structure for vertical axis wind turbine.
