RISDebris Damage in Rolling Bearings and Its Effects on Fatigue Life
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Predictions of fatigue life from debris indented roller bearings are calculated by the methods described by Webster, Ioannides, and Sayles [9] and presented as a comparison to the actual fatigue ...
A Simplified Diagram of Seizure Criteria for Lubricated Sliding Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper describes an attempt to include surface roughness effects in the conventional pressure-velocity (PV) map for lubricated sliding surfaces. The criteria proposed involve two different ...
A Numerical Model for the Elastic Frictionless Contact of Real Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A computer model for the dry, frictionless contact of real rough surfaces is presented. The model uses data directly recorded from a stylus measuring instrument and as a confirmation of the ...
Thermo-Mechanical Model for Moving Layered Rough Surface Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical model designed to simulate a moving line contact of two rough layered bodies is presented. Fourier transforms are used to obtain fundamental solutions to relevant differential equations ...
A Numerical Model for the Contact of Layered Elastic Bodies With Real Rough Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical model for the two-dimensional dry, frictionless contact of two elastic bodies with real rough surfaces, where one body has a rigidly bonded surface layer, is presented. The model ...
Stiffness of Machine Tool Joints: A Random-Process Approach
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A random-process surface model of elastically yielding asperities with a gaussian height distribution is proposed to represent the deflection of a machine tool joint. A passband of surface ...
Measurements of the Statistical Microgeometry of Engineering Surfaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surface and profile measurements and their resulting statistics, based on samples of up to half a million heights, are compared and their interrelationship examined for several common engineering ...
Numerical Contact Model of a Smooth Ball on an Anisotropic Rough Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A numerical elastic-plastic contact model of a smooth ball on a directionally structured anisotropic rough surface is presented. The contact model is tested on three types of surface contact ...
Contact Analysis of a Smooth Ball on an Anisotropic Rough Surface
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of surface roughness and waviness upon the real contact areas, gaps between contact spots, and asperity contact pressures were studied. The distribution of real areas, gaps, and ...
Effect of Roughness and Sliding Friction on Contact Stresses
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The stress distributions associated with smooth surfaces in contact are rarely experienced in practice. Factors such as surface roughness, lubricant films, and third body particulates are known ...
