Comparisons of Experimental and Theoretical Dynamic Rotor-Bearing Behavior Using Gas Lubrication.
Abstract
The report presents the results of an investigation into the adequacy of presently available theory in predicting the dynamic behavior of a rotor supported in hydrostatic and hydrodynamic gas lubricated journal bearings. Measurements of critical speeds, threshold of instability speeds, gas flow rates, and rotor whirl frequencies for several rotors supported in hydrostatic and hydrodynamic journal bearings were made and compared to theoretical predictions. Variables investigated were bearing load, bearing supply pressure, bearing and gas temperature, and type of bearing supply gas. Good agreement between the experimental and theoretical results was obtained. (Author)
