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.

The paper uses the finite element software ANSYS to establish a 1.5 MW horizontal-axis wind turbine tower model as an example and works on the modal analysis. The modal analysis takes into account the totalmass of wind rotor and nacelle and assumes the bottom of the wind turbine tower is fully constrained. The result shows that the natural frequency of the 1.5MW wind turbine tower is not coincident with the excitation frequency of the wind turbine, and the wind turbine can operate stably at the design condition.

Wind Turbine Airfoil

In this work, a new approach for aerodynamic optimization of horizontal axis wind turbine (HAWT) airfoil is presented. This technique combines commercial computational fluid dynamics (CFD) codes with differential evolution (DE), a reliable gradient-free global optimization method. During the optimization process, commercial CFD codes are used to evaluate aerodynamic characteristics of HAWT airfoil and an improved DE algorithm is utilized to find the optimal airfoil design. The objective of this research is to maximize the aerodynamic coefficients of HAWT airfoil at the design angle of attack (AOA) with specific ambient environment. The airfoil shape is modeled by control points which their coordinates are design variables. The reliability of CFD codes is validated by comparing the analytical results of a typical HAWT airfoil with its experimental data. Finally, the optimal design of wind turbine airfoil is evaluated about aerodynamic performance in comparison with existing airfoils and some discussions are performed.
