In this paper, the mechanism and dynamic stability of gas-lubricated bearing are considered. The pressure distribution which is generated in compressible fluid at the gap of bearing is calculated. The equation of motion is derived using the fluid force acting on journal which is calculated from the pressure distribution. Based on the derived equation, the numerical simulation of the dynamic behavior of the journal is performed and the stability of the behavior of the journal is investigated. Finally parameter studies are discussed.
