Abstract

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