Abstract. The main purpose of this paper is to define a methodology to determine the analytical approximate closed-form expression of probabilistic characteristics of load capacity of liquid-lubricated journal bearings in the case of a steady flow regime. Influence of random change of basic geometrical parameters of journal bearings (gap value and eccentricity) on the load capacity of bearing is considered. It is shown that the actual value of hydrodynamic force in bearing can substantially differ from a calculation one. The got results confirm the necessity of application of such approach at consideration both geometrical and operating parameters of bearing, for example, axes misalignment, deviation of surface form, roughness and others, which have casual nature too.
The paper presents the results of numerical simulations (CFD) of hydrodynamic thrust slide bearings lubricated
with magnetorheological (MR) fluid. The analyses were carried out to evaluate the influence of the rheological
properties of the lubricant, as well as the geometry of the bearing's thrust pad surface. Bearing load conditions
were considered on the key functional features of the system, i.e. axial force and torque. The paper presents
a comparative analysis of various geometries of thrust bearings and points out possible functional features of
hydrodynamic thrust bearings lubricated with fluids with controlled rheological properties.
