The circular elastic metalplastic padsupported by the center point is taken as the research object Based on thelubrication theory
the mathematical model of thrust bearing is established Thesimulation analysis is carried out by using finite element software
and thelubrication performance is simulated The conclusion shows that the oil filmpressure causes concave deformation of pad surface
the oil film temperaturecauses convex deformation of pad surface
and overall deformation of bearingbushing is concave According to the deformation of bearing pad
the bearing padsurface is modified into a mediumconvex surface with a slope thickness of 005mmand a slope length of 8mm Under the same working conditions
the minimum oilfilm thickness decreases with the increase of elastic composite layer thicknessand the minimum oil film thickness increases with the increase of steel basethickness When the elastic composite layer is thicker to 10mm
the maximum oilfilm temperature appears peak value
which is not conducive to bearing heatdissipation The change of steel base thickness has little effect on the maximumoil film temperature and the overall bearing temperature
