Finite Element Analysis for the Wind Resistance of the Tower of Wind Turbine

1MW variable speed constant frequency wind turbine tower of steel structure is analyzed by using the software ANSYS, the coupling between the wind and the tower is realized through the order coupling method. The maximum Von Mises stress and the deformation of the tower in the case of limit loads are obtained, and then these results are compared with that without wind load. Comparison result shows that the effect of wind load on the tower’s displacement along the wind speed is great, and the maximum Von Mises stress of the tower becomes larger after considering the influence of wind load, the increase extent is determined by wind load case.
