Simulation and optimum design of journal porous metal bearing under elastohydrodynamic lubrication

Abstract

With some new simulation methods and software tools it is possible to make qualitative analysis of sliding bearing behavior taking elastic deformations in account. This paper presents simulation and structural optimization of journal porous metal bearing under complex load distribution. Surface of porous metal bearing is loaded inside with pressure distribution that is calculated by hydrodynamic lubrication theory. Besides there is also frictional force loading inner surface and nonuniform temperature distribution on bearing volume. The structure analysis is made for each kind of load separately and for complex load distribution of bearing. This simulation is realized by finite elements method (FEM) in structure analysis module of CATIA V5 software. Based on this simulation in second part of paper is given parameter optimization of porous metal bearing with taking elastic deformations of bearing shell into account.
