This book was released on 1971 with total page 54 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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).
