A mass-conserving, mode-based elastohydrodynamic lubrication model, which includes combined effects of journal and sleeve elasticity, is described. Application to a sample cylindrical bearing system (geometrically similar to automotive main and connecting rod bearings) shows that relative displacement of an elastic journal and sleeve can be represented by a set of mode shapes which are qualitatively similar to those obtained with a rigid journal, while the corresponding mode eigenvalues are found to be dependent on journal elasticity. Performance evaluation under steady and pure squeeze loading shows that a sufficiently compliant hollow journal can reduce film pressure and improve film thickness when compared with its rigid counterpart.
