Abstract In this paper the finite element analysis was carried out for a composite vertical axis wind turbine with lift-drag combined starting structures to ensure the structure safety of a vertical axis wind turbine(VAWT). The static and modal analysis of rotor of a composite vertical axis wind turbine was conducted by using ANSYS software. The relevant contour sketch of stress and deformation was obtained. The analysis was made for static structural mechanics, modal analysis of rotor and the total deformation and vibration profile to evaluate the influence on the working capability of the rotor. The analysis results showed that the various structure parameters lie in the safety range of structural mechanics as given in the relative standards. The analysis showed the design safe to operate the rotor of a vertical axis wind turbine. The methods used in this study can be used as a good reference for the structural mechanics′ analysis of VAWTs.
