ABSTRACT
The main objective of this work is the evaluation of the performance of an EHD (elastohydrodynamic) lubrication reduced model for angular contact ball bearings. The multilevel numerical integration algorithm is applied to solve the EHD lubricated contact equations and the numerical results are optimized to adjust an equivalent force versus displacement curve of a reduced model based on equivalent nonlinear stiffness and linear damping coefficients of the bearing. The rotor-bearing finite element model is therefore built, allowing the comparison with experimental tests obtained from the literature.
