Frictional contact analysis in a spherical roller bearing
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.
