AEROELASTIC SIMULATION OF A ROTATING A WIND TURBINE BLADE (SOLVING THE FLAPEWISE EQUATION)

摘要

The aim of work is to compute dynamic stresses acting on wind turbine blades. These stresses are essential in predicting the fatigue. This analysis has a particular importance knowing that the major cause of wind turbine failure is fatigue. The turbine rotor is exposed to wind loading of a cyclic nature, making it vulnerable to cumulative fatigue damage. The approach used in this work is based on the analysis of the blade movement, by solving blade motion equation, in order to obtain dynamic stresses.
