What Happened to You, Buddy? The Evaluation of Blade Bearings

Authors: Dr.-Ing. Matthias Stammler, Karsten Behnke Whenever we have the opportunity to look at damaged bearings, we as scientists love to do so. Be it the bearings we tested in our own lab or bearings directly from the field, it…

Rotor blade bearings: Accurate prediction of fatigue life

Predicting the fatigue lifetime of rotor blade bearings is a particularly difficult task as the use of existing calculation methods requires a comprehensive understanding of the systems and the methods are scarcely validated for the unique blade bearings with their extraordinary load situations.
