Then, the influences of the critical parameters, i.e. tower thickness, tower height and top mass, to the eigenfrequency, buckling load, stiffness and stress of the wind turbine system are analyzed. The results show that the mechanical behavior of wind turbine tower is sensitive to all of the parameters. Hopefully, the parametric analysis will provide the foundation to the wind turbine system optimal design.
