Optimum design for porous metal bearing

Porous metal bearings as a special sort of sliding bearing are common in use today in most of machines. Their main characteristic is the possibility of selflubrication during operating life. The aim of this paper is to apply already developed basic concept for optimum design of sliding bearings generally on this sort of selflubricating porous metal bearing and make their optimum design study. The study gives objective functions and some equality and inequality constrains based on hydrodynamics lubrication theory. The optimum design model and procedure are realised through developed computer programme followed by numerical examples and results analysis.
