RISEffect of Roughness Orientation on the Elastohydrodynamic Lubrication Film Thickness
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Effect of roughness orientation on lubricant film thickness has been an important issue of surface design, attracting much attention since the 1970 s. A systematical study, however, is still needed for various contact ...
On the Stribeck Curves for Lubricated Counterformal Contacts of Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The “Stribeck curve†is a wellknown concept, describing the frictional behavior of a lubricated interface during the transition from boundary and mixed lubrication up to fullfilm hydrodynamic/elastohydrodynamic ...
Experimental and Numerical Investigations of the Stribeck Curves for Lubricated Counterformal Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The Stribeck curve is an important means to demonstrate the frictional behavior of a lubricated interface during the entire transition from boundary and mixed to full-film lubrication. In the present study, a new test ...
A New Singularity Treatment Approach for Journal Bearing Mixed Lubrication Modeled by the Finite Difference Method With a Herringbone Mesh
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Steadystate mixed hydrodynamic lubrication of rigid journal bearing is investigated by using a finite difference form of the Patir–Cheng average Reynolds equation under the Reynolds boundary condition. Two sets of ...
Journal Bearing Surface Topography Design Based on Transient Lubrication Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A transient mixed lubrication model is used to study the performance of a journal bearing subjected to impulse loading, considering mass conservation and the effects of asperities on flow and contact, to explore a novel ...
Housing Profile Design for Improved Apex Seal Lubrication Using a Finite Length Roller Elastohydrodynamic Lubrication Model
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Finite-length roller contacts are found in apex seal-housing interfaces in rotary engines, as well as in many other mechanical systems, such as those at the interfaces of meshing gear teeth, cam followers, and roller ...
Understanding Additive Manufacturing Processes for Surface Texturing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Additive manufacturing (AM) is an important addition to fabrication technology due to its flexibility in shape and material processing and ability to reduce waste compared to other fabrication methods. However, ...
Erratum: “Profile Design for Misaligned Journal Bearings Subjected to Transient Mixed Lubrication” [ASME J. Tribol., 2019, 141(7), p. 071701; DOI: 10.1115/1.4043506]
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In the original publication, Fig. 5 is incorrect. The actual applied loads used for all the simulations can be found in the corrected figure below with a peak vertical load of 13.7 kN in magnitude.
Contact Yield Initiation and Its Influence on Rolling Contact Fatigue of Case-Hardened Steels
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Stress distributions and plastic deformation zones are factors directly influencing the fatigue life of components under cyclic contact. An effective approach to improving the resistance of a steel to contact fatigue failure ...
Generalized MEMT-Field Reynolds Equation With Application to Electric Polarization in Lubrication
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. Lubricants used in electrically powered machinery, such as electric vehicles (EVs) and wind turbines, operate under complex mechanical, electric, magnetic, and thermal (MEMT) environments that can significantly ...
