A New Theoretical Model for Analysis of the Fluid Film in the Cavitation Zone of a Journal Bearing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies of the cavitation zone in the journal bearing indicate that a sublayer of lubricant adheres to the journal surface. Based on this observation, it is proposed in the present ...
Unbalance Response of a Dual Rotor System: Theory and Experiment
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A dual rotor rig is developed and is briefly discussed. The rig is capable of simulating dynamically the two spool aeroengine, though it does not physically resemble the actual aeroengine ...
Dynamically Loaded Finite Length Journal Bearings: Analytical Method of Solution
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A closed-form pressure distribution, using a combination of short- and long-bearing approximations, is proposed for dynamically loaded journal bearings. The angles for start and finish of positive ...
A Hybrid Solution Scheme for Performance Evaluation of Crankshaft Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the past few decades the research efforts towards efficient solutions of crankshaft bearing using both rapid (e.g., analytical, semi-analytical, curve fits) and rigorous numerical approaches ...
Thermal Analysis of Noncircular Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The present work is on prediction of temperature distribution in noncircular journal bearings and the surrounding solids. Three forms are studied, viz. two-lobe, elliptical and orthogonally displaced ...
A Numerical Approach to the Stability of Rotor-Bearing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stability characteristics of a rotor-bearing system which indicate the threshold of instability are generally obtained by applying the Routh-Hurwitz criterion to the characteristic polynomial. ...
