Abstract
In order to understand the load distributions and the safety of large-scale wind turbine blades under various wind conditions, ANSYS finite element analysis (FEA) software package was often used for investigation. The pressure distribution on the blades was calculated by use of ANSYS CFX flow field analysis module . The resulting pressure distribution was mapped on to the finite element model of the blades using distributed forces as the loading conditions. After finite element structural analysis, the Tsai-Wu failure criterion was used for damage prediction. In the present study, the flow fields and structures for four types of turbine blades were investigated under the aforementioned methodology. First, the V47 and V80 blades were studied for damage prediction. The results of V47 blade analysis were compared against experimental data for verification of the accuracy. Second, based on the blade design formulas and the turbine blade data released by the National Renewable Energy Laboratory, the 3.6-MW and 5-MW blades were designed, plotted and analyzed. With various types of lamination, the costs, strengths, and weights of the proposed laminate composite blades are studied and compared.
