Structural response analysis of wind turbine under different wind speeds

Abstract Taking a 2 MW horizontal axis wind turbine in farm Northwest China as the research object, structural response analysis of considering fluid structure coupling effect under different inflow was carried out by using ANSYS Workbench software. The results show that when incoming speed is cut-in speed, displacement and stress change slightly; between cut-out law same. maximum increase with blade located tip, concentrated middle blade; tower at top, bottom. have important reference value for design safe operation turbine.
