Research on dynamics of icing wind turbine blade based on geometrically exact beam theory
In this paper, the geometrically exact beam theory (GEBT) and blade element momentum theory (BEMT) are used to establish the aeroelastic coupling model for analyzing the dynamics of flexible icing wind turbine blades. The developed model is verified by several examples. Besides, three nonuniform wind inflow modes are introduced in this paper. Then, the effects of icing mass and icing aerodynamics are studied respectively, and the simulation results show that the mass and aerodynamic effects of icing have different influences on blades. Next, the electromechanical characteristics of icing blades under three nonuniform wind inflow modes are calculated and analyzed respectively, and the dynamic responses under different pitch angles are compared. Furthermore, to obtain the dynamic characteristics of icing blades as closely as possible to the actual operation conditions, the case of icing blades under above factors simultaneously is simulated and analyzed. Finally, the several main conclusions of icing blades are summarized.
期刊介绍：
The Journal of Sound and Vibration (JSV) is an independent journal devoted to the prompt publication of original papers, both theoretical and experimental, that provide new information on any aspect of sound or vibration. There is an emphasis on fundamental work that has potential for practical application.
JSV was founded and operates on the premise that the subject of sound and vibration requires a journal that publishes papers of a high technical standard across the various subdisciplines, thus facilitating awareness of techniques and discoveries in one area that may be applicable in others.
