Frictional contact analysis in a spherical roller bearing [PDF]
Journal of Computational Design and Engineering, 2022 Abstract Numerical analyses of the roller–raceway contact have been carried out in a spherical roller bearing using frictional contact models of different complexity. The models used in the study include an implementation of Kalker’s exact contact theory named CECT (Conformal Exact Contact Theory) and detailed Finite Element models.

Dynamic modelling of slip in a wind turbine spherical roller main bearing [PDF]
Forschung im Ingenieurwesen, 2023 This paper considers the problem of the dynamic modelling of macroslip in spherical roller bearings. By revisiting the fundamental physics which drive these systems, potential issues in existing models have been identified. Furthermore, in pure rolling conditions it was found that governing differential equations become “stiff”, requiring the use of ...
