Wind Turbine Tower

In order to realize the buckling strength design for the opening door of the large-scale horizontal axis wind turbine tower, the method combined with the engineering method and the FEM was presented. The FE model of the door was established. The first-order buckling eigenvalues and buckling modes for three different structures were calculated and analyzed. Based on engineering method, the stress and buckling strength for the sections of tubular tower were obtained. Corrected by FEM results, the tower door with opening buckling strength were checked by engineering method. The results were compared with those by FEM. The safe design structure anti-buckling were presented. The method presented in this paper is feasible and effective for the opening door design in large-scale horizontal axis wind turbine tower.
