Abstract:

As an important rolling connection of the wind turbine, yaw slewing bearing plays a critical role in the structure reliability. Therefore, effective health monitoring of a slewing bearing to execute timely maintenance or replacement have attracted significant interest. In order to monitor working conditions on line, various sensors have been used. This paper discussed the installation approaches of various sensors in a yaw slewing bearing, and analyzed the effect of local structure change on the fatigue life of a 1.5MW slewing bearing by MSC.FATIGUE, and thus providing an effective reference for structural design of a smart slewing bearing.
