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…

Wind farm optimization: Higher yield thanks to intelligent operational management

When the wind passes through the rotor disc of a wind turbine with its rotating blades, the wind speed behind the turbine is reduced – the turbine extracts kinetic energy from the wind to convert it into electrical energy. This…

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.
