Refined Solution of Pneumatic Hammer Instability of Inherently Compensated Hydro¬static Thrust Gas Bearings

摘要

An externally-pressurized gas thrust bearing was analyzed for both static and dynamic characteristics. The bearing is fed through an inherently compensated restrictor into a shallow packet. The analysis gave special attentions to the significance of the recent finding of restrictor flow (Ref. 4), the trade-off consideration between static stiffness and stability margin, and the effects of the pocket depth.
