RESUMO
With the need of time reduction on mechanical projects, the use of computational models for the analysis of mechanical components becomes mandatory in order to avoid excessive physical tests. Based on this assumption, is necessary to study the dynamic of previously assumed rigid components, as the rolling elements bearings, and thus knowing its influence on the complete system. Utilizing a multi-level finite difference method, the lubrication condition on the contact in bearings under Elastohydrodynamic (EHD) transient lubrication was evaluated. Therefore the dynamic characterization of the contact was possible, adjusting the oil film to a nonlinear spring-damper set. Hence a flexible joint is introduced in the bearing, making it possible its dynamic analyses as part of the system
