Analysis of airfoil deformation of wind turbine
摘要
Abstract
In previous studies on blade deformation of wind turbines,generally only focus on waving,torsional deformation.But in fact,the airfoil curvature,thickness changes caused by flexible deformation of the airfoil itself also have a great impact on the aerodynamic performance.In this paper,a 5 MW wind turbine of NERL is used as an example to calculate the blade load of wind turbine using Bladed software and then the load is loaded into the ANSYS finite element model by MPC multi-point constraint to study the deformation of the flexible blade airfoil section.It is shown that the torsional deformation of airfoil cross section is not the whole waving and torsional deformation.In fact,the amplitude of torsion from the web to the trailing edge is larger than that from the web to the leading edge.The deformation of the airfoil section itself will also affect the aerodynamic performance of blades.关键词
