A Conformal Lubricated Contact of Cylindrical Surfaces Involved in a Non-Steady Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A non-steady problem for a conformal elastohydrodynamically lubricated (EHL) contact of two infinite cylindrical surfaces with parallel axes is considered. It takes into account the elasticity of ...
Contact Fatigue of Rough Elastic Surfaces in Two-Dimensional Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Solution of a contact problem for a rough elastic half-plane is considered. Surface roughness is assumed to be small and stochastic. A perturbation solution of the problem for relatively small ...
Fatigue Modeling for Elastic Materials With Statistically Distributed Defects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper is devoted to formulation and analysis of a new model of structural fatigue that is a direct extension of the model of contact fatigue developed by (2000, STLE Tribol. Trans., 43, ...
Formulation and Analysis of EHL Problems for Soft Materials
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a qualitative and numerical analysis of the new formulation of a steady problem for lubricated rollers made of elastic materials with low Young’s modulus. The feature that ...
Modeling of Line Contacts With Degrading Lubricant
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A plane isothermal elastohydrodynamic problem for a lubricated line contact is studied. The lubricant represented by a base stock with some polymer additive undergoes stress-induced degradation ...
Lubricants With Non-Newtonian Rheology and Their Degradation in Line Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A plane isothermal elastohydrodynamic problem for a line contact lubricated by a degrading fluid with non-Newtonian rheology is studied. The lubricant is represented by a base stock with a ...
Defects of the Classic Formulation of a Nonsteady EHL Problem for a Journal Bearing. New Problem Formulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A nonsteady problem for an elastohydrodynamically lubricated (EHL) journal bearing is considered. It is shown that under certain circumstances contact pressure and shaft normal velocity are ...
Scale Effects in Generalized Newtonian Elastohydrodynamic Films
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The estimation or prediction of elastohydrodynamic lubrication (EHL) film thickness requires knowledge of the lubricant properties. Today, in many instances, the lubricant properties have been ...
