Short summary
Most important for finite-element models is validation to ensure reliable results. To the knowledge of the authors, all publicly available large rolling bearing models are not validated. This work introduces a finite-element model of a 5 m roller bearing as a wind turbine blade bearing. The authors investigated the influence of different bolt preloads on the bearing rings and validated the model against experimental data using a large blade bearing test rig.
