Static and Dynamic Characteristics of Cirular Aerostatic Porous Thrust Bearings.

open access: yesTRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1996
Recently brittle porous materials such as graphite and advanced ceramics have been used in the fabrication of aerostatic bearings because gas flow through these porous materials can be limited to a small amount. However, aerostatic bearings consisting of these porous materials are prone to cause pneumatic hammer instability. Therefore, it is considered
