摘要

AbstractThe continuous demand for higher power density leads to a very challenging operational environment for sliding bearings regarding pressures and deformations. Understanding of the deformation behavior of heavily loaded bearings becomes even more pronounced when modern hybrid multilayer designs are considered. The aim of this study is to develop a numerical, multi-physical model for the evaluation of journal bearing performance. Hydrodynamics were based on the Reynolds equation and deformations were calculated using the integrated finite element method. Elastic and thermal deformations have a significant effect on bearing performance and those deformations can be adjusted with properties of polymer layer. The design of hybrid bearings is delicate and their properties must be tailored according to the operating conditions.Highlights?Multi-physical model for hybrid journal bearings is presented.?Sensitivity of thermal boundary conditions of the model is studied.?Good potential of polymer hybrid bearing is observed.?Hybrid bearings are case sensitive and need to be tailor-made.]]>
