Abstract
On the basis of the finite element analysis model of the wind turbine flange, this paper studies the fatigue damage of the MW wind turbine flange, analyzing the fatigue stress of the wind turbine flange with MSC.Marc/Mentat software, realizing load simulation of flange fatigue case with Bladed software, and calculating the fatigue loading spectrum of the flange with the method of rain flow circulation count. The fatigue damage calculation method which combines the rain flow circulation count method with Palmgren-Miner linear cumulative damage law, is proposed to modify the S-N curve of the flange material according to GL standard. The result shows the method feasible and reliable which provides one more accurate analysis idea for the fatigue life of the wind turbine generator system top flange.
