Paper Abstract

The pneumatic hammer in rectangular aerostatic thrust bearings with groove is analyzed using perturbation theory. Routh stability criterion was used to evaluate the critical condition of pneumatic hammer in rectangular aerostatic thrust bearings with groove, and the influence of supply pressure, throttle area, groove area, and thickness of film on aerostatic thrust bearings. It was found through analysis that the change rate of stiffness and the volume ratio of aerostatic bearing could be used to analyze the pneumatic hammer in rectangular aerostatic thrust bearings with groove. At a certain film thickness, the stability of aerostatic bearings could be improved by reducing supply pressure, increasing throttle area and decreasing groove area to facilitate the design of a general aerostatic thrust bearing.
