Elastohydrodynamic Lubrication of Conformal Bearing Systems

It is well known that structural elasticity plays a prominent role in the performance of fluid film bearing systems. Previous work in elastohydrodynamic (EHD) bearing lubrication has focused on the development of computational algorithms that are particularly useful for conformal bearing systems subjected to dynamic loading. This paper reports on the means to integrate a mode-based EHD lubrication model with substructuring and superlement capabilities in ANSYS to predict bearing performance (film thickness, film pressure) and structural performance (distributed stresses) for dynamically loaded journal bearings. An automotive connecting rod is presented as a case study.
