On finite element model for hydrodynamic journal bearing with micropolar lubrication

Abstract

The aim of the present work is to develop a finite element model for calculating the pressure of a hydrodynamic fluid-film bearing with micropolar lubrication. The mathematical model is based on the generalized Reynolds equation. Two types of bearings, immersed and with axial lubrication, are considered, for which effective and robust pressure field calculation algorithms are proposed based on the finite element method. In following, the pressure fields are used to determine the static and dynamic integral bearing characteristics.
