Abstract
In the light of the structural features of the wind turbine tower and force characteristics, the mechanical model of the variable cross-section tube tower is established. Based on the elastic stability theory, the buckling of tower is studied, and the critical force formula of the tower under the concerted action of concentrated force and gravity is deduced. Calculation models are numerically simulated for the stability of the tower by using the finite element software ANSYS, and corresponding critical load is obtained. The results show that the finite element models are feasible in engineering application, and the analysis provides a theoretical basis for structural design of wind turbine.
