Numerical Simulation of Deflections for Rotating Wind Turbine Blades Based on Aeroelastics and Aerodynamics
摘要
Abstract
Based on the structural dynamic equations of blades, an aeroelastic model of a rotating rotor and the numerical simulation method of the deflections were presented under aerodynamic loads and centrifugal forces. Coupling the aerodynamic characteristics and the structure stress, the flapwise and edgewise loads and deflections of the rotating blades were calculated and plotted by using this model. Finally, the computation was completed for a 2MW wind turbine. The deflections of the blades under different wind speeds and different rotating time were given to validate the reliability of the model presented herein. The results have very important significance to estimate the vibration performance, fatigue life of the blades and to direct the design of high performance blades.关键词
