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.

The node-based smoothed finite element method (NS-FEM) proposed recently has shown very good properties in solid mechanics, such as providing much better gradient solutions. In this paper, the topology optimization design of the continuum structures under static load is formulated on the basis of NS-FEM. As the node-based smoothing domain is the sub-unit of assembling stiffness matrix in the NS-FEM, the relative density of node-based smoothing domains serves as design variables. In this formulation, the compliance minimization is considered as an objective function, and the topology optimization model is developed using the solid isotropic material with penalization (SIMP) interpolation scheme. The topology optimization problem is then solved by the optimality criteria (OC) method. Finally, the feasibility and efficiency of the proposed method are illustrated with both 2D and 3D examples that are widely used in the topology optimization design.
