Development of a Method for the Prediction of Pressure-Viscosity Coefficients of Lubricating Oils Based on Free-Volume Theory
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A simple method based on free-volume theory to predict the pressure-viscosity coefficients of liquid lubricants has been developed. The method only requires the viscosity-temperature relationship ...
Prediction of Bulk Moduli for Mineral Oil Based Lubricants, Polymer Solutions, and Several Classes of Synthetic Fluids
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study involves the development of correlating equations for the prediction of the bulk moduli of mineral oil-based lubricants, polymer containing lubricants, and several classes of synthetic ...
Modeling of Temperatures in the Conjunction of a Vapor-Lubricated Four-Ball Wear Tester
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies have shown that solid films formed from vapor-delivered lubricants can provide effective lubrication for load-bearing systems at elevated temperatures. A model is developed to ...
The Viscous Behavior of Polymer Modified Lubricating Oils Over a Broad Range of Temperature and Shear Rate
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A high-shear capillary viscometer was used to determine the viscosity of mineral oil lubricants containing an olefin copolymer up to shear rates of a million reciprocal seconds. Comprehensive ...
Contact Fatigue Failure of Ultra-High Molecular Weight Polyethylene Bearing Components of Knee Prostheses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of this work has been to study the origin of surface failures in UHMWPE tibial bearings of total knee replacements. Earlier examination of hundreds of retrieved prostheses, along ...
