The static characteristics and damping characteristics of groove-compensated annular thrust air bearings are analyzed. The finite element method is applied to obtain a numerical solusion of the Reynolds equation, and a computer simulation method is developed to obtain a dynamic response of the shaft supported by the bearing. Based on the computed results, the effects of various specific design parameters of the bearing on the static characteristics and the damping characteristics are discussed. The principles for the optimization of the bearing design are proposed.
