Fluid Film Bearings

1993
Fluid film bearings are commonly used in heavy rotating machines because they possess not only high load carrying capacity but also inherent damping properties. Unlike rolling element bearings, fluid film bearings are an important machine element which offers, in addition to support stiffness, substantial damping to insure rotordynamic stability.

Stability of rotors in compressible fluid-film bearings

Journal of Propulsion and Power, 1987
A power-shaped multipad hydrodynamic journal bearing working in compressible fluid is described here that is suitable for high-speed turbomachines. This type of bearing is much simpler than tilting pad or foil journal bearings and will provide satisfactory results for machines intended to operate under relatively constant environmental and operating ...
