College of Science & Engineering

Summary of Project

Wind turbine blade pitch is controlled by the blade pitch bearings. This is done to maximise power generation when wind speeds are low and to protect the blades during high wind events. The reliability of these bearings is therefore important for both operational and efficiency reasons. Replacing these bearings is very costly. A metallurgical examination by optical and scanning electron microscopy of a failed pitch bearing raceway will be carried out to identify the failure modes. Finite element analysis will be conducted to model the failure that is consistent with the metallurgical examinations. This will entail modelling the various operational modes that the wind turbine blade pitch bearings experience. Modifications of the pitch bearings can then be modelled and tested.
