Abstract：The water lubrication performance of elastic-metal-plastic(EMP) thrust bearings was affected by liquid inertia force and interfacial slip. The Reynolds equation in the cylindrical co-ordinates with consideration of liquid inertia force and interfacial slip was derived from continu-ous equation and Navier-Stokes equation. The numerical computation of Reynolds equation was completed by a finite differential method. The results show that the water film pressure and the load capacity of the elastic-metal-plastic thrust bearing were decreased by 10% when the in-terracial slip happened. The film pressure and the load capacity were improved by 1% when the liquid inertia force was included. With the increasing of the rotational speed, the water film pressure and the load capacity of the elastic-metal-plastic thrust bearing were reduced by 50%.
