Numerical analysis of a circular hydrostatic thrust bearing with an elastic pad is performed. Under the conditions of steady state, axi-symmetry and fluid film lubrication, the Reynolds and elastic equations are solved numerically. The effects of the pad thickness and the supply pressure on the frictional torque, leakage flow rate, power loss and the bearing stiffness are examined. In conclusion, as the pad is thinner and/or the supply pressure is higher, the elastic deformation becomes marked, which results in the fact that the central gap, the stiffness and the power losses decrease.
