Vibration Modeling and Analysis of a Wind Turbine Blade based on Third-Order Structural Nonliearities, Ph.D. Dissertation Sharif University of Technology ; Behzad, Mehdi (Supervisor) ; Haddadpour, Hassan (Co-Advisor) ; Moradi, Hamed (Co-Advisor)
Abstract
Aiming to improve the extraction performance of wind energy has led to the noticeable increase of the structural dimensions in the modern wind turbines. The larger blade with more flexibility experiences large structural deformation even under nominal operational loading, so the nonlinear modeling and analysis of these structures have become as important subject of the recent wind turbine researches. In this dissertation, the geometrical exact model of the rotating wind turbine blade under the effects of the tower tip's motion, and also the operational loading comprising the aerodynamic and gravitational loadings is presented. In this way, the geometrical exact beam formulation is developed...
