The Problem of Constructing Optimal Processable Profiles of Plain Bearings

The problem of microgeometry profiling of the lubricating layer of an irreversible plain bearing is considered with the assumption of the maximum lift force on the basis of a Rayleigh pocket in order to construct profiles easy to manufacture. To this end the lift force dependence on several selected parameters, which most accurately approximate the considered profile to the profile of the global extremum, is investigated. The formulated problem of parametric optimization is solved using the software packages IOSO and modeFrontier, whereas the pressure field in the bearing is determined by the Navier–Stokes equations using the ANSYS/CFX. The results may be used to construct optimal processable profiles of plain bearings applied in various power engineering and other machines and devices.
