Effect of Rate of Viscosity Variation on the Performance of Journal Bearings
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Variations in viscosity within the film is known to have a pronounced effect on journal bearing performance. Lubricants of the same grade with the same viscosity at a particular temperature ...
Performance of a Powder Lubricated Journal Bearing With WS2 Powder: Experimental Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Previous investigations have demonstrated the principle and feasibility of quasi-hydrodynamic lubrication using powders. With conventional lubricants, the hydrodynamic behavior of a journal bearing ...
Frequency Effects on the Stability of a Journal Bearing for Periodic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, stability of a journal bearing is numerically predicted when an unidirectional periodic external load is applied. The analysis is performed using a cavitation algorithm, which ...
The Solution of the Elrod Algorithm for a Dynamically Loaded Journal Bearing Using Multigrid Techniques
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical solution to a theoretical model of vapor cavitation in a dynamically loaded journal bearing is developed, utilizing a multigrid iterative technique. The method is compared with a ...
Analysis of Starvation Effects on Hydrodynamic Lubrication in Nonconforming Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Numerical methods were used to determine the effects of lubricant starvation on the minimum film thickness under conditions of a hydrodynamic point contact. Starvation was effected by varying ...
