Abstract :
A finite element model of 1.5MW wind turbine blade is established and verified. The dynamic properties of blade with eccentricity fault are analyzed. The results show that the dynamic response is linearly growing with the increase of mass when different mass-blocks are placed at the same position, and the dynamic response of the third out-of-plane vibration is gradually increasing from the blade root to tip when the same mass-block is placed at different positions. The present study provides a new theoretical basis for eccentricity fault diagnosis of large wind turbine blade.
