The characteristics of spiral grooved thrust air bearings, i. e., stiffness, load capacity, power loss and the fraction of critical damping, are analyzed. The finite element method and the computer simulation method are applied to obtain the numerical solution of the Reynolds equation. Based on the computed results, the effects of various specific design parameters of the bearing on the load-carrying performance and the damping characteristics are discussed. The principles for the optimization of the bearing design are proposed.
