RISImage-Based Procedure for Biostructure Modeling
Publisher: American Society of Civil Engineers
Abstract: For high-resolution medical images, an image-based procedure is developed in strong form to perform microstructure analysis. Consider heterogeneous biomaterials such as bone tissue with porous composition—the associated ...
Effects of Thermal Conductivity of Contacting Surfaces on Point EHL Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With actual and virtual materials, the effects of the thermal conductivity of contacting surfaces on EHL are investigated through experimental analyses using the optical interferometry technique ...
Formation Mechanism of Steady Multi-Dimples in Thermal EHL Point Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: With optical interferometry technique, an interesting multi-dimple phenomenon has been discovered under pure-sliding conditions in the point contact between a glass disk and a 3-inch diameter steel ...
A Numerical Analysis for TEHL of Eccentric-Tappet Pair Subjected to Transient Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A full numerical analysis is carried out to simulate the thermal elastohydrodynamic lubrication (TEHL) of an eccentric-tappet pair. Comparisons between thermal and isothermal results are given to ...
A Non-Newtonian TEHL Analysis of Tilting-Pad Bearings Subjected to Inlet Pressure Build-Up
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The characteristics of the infinitely wide tilting pad bearings operating under thermal elastohydrodynamic lubrication (TEHL) condition were investigated theoretically. The power-law rheological model ...
Adaptive Velocity Control of DC Motors With Coulomb Friction Identification
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new dc motor control technique for the Coulomb friction compensation is proposed. The technique uses an adaptive velocity control scheme for a dc servo motor with on-line estimated parameters, ...
Thermal and Non-Newtonian Numerical Analyses for Starved EHL Line Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper focuses on the mechanism of starvation and the thermal and non-Newtonian behavior of starved elastohydrodynamic lubrication (EHL) in line contacts. It has been found that for a starved ...
Closure to “Discussion: ‘Quantitative Comparisons Between Measured and Solved EHL Dimples in Point Contacts,’ (Yang, P., Kaneta, M., and Masuda, S., 2003, ASME J. of Tribology, 125(1), pp. 210–214)”
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The authors are grateful for the comments on this paper and are encouraged that the discusser agrees that the dimple phenomena are generated by the temperature-viscosity effect.
Effects of Compressive Heating on Traction Force and Film Thickness in Point EHL Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The effects of compressive and viscous heatings of lubricating fluid on the traction force and film thickness are investigated under low slide-roll ratios by thermal EHL analyses based on the ...
Formation of Steady Dimples in Point TEHL Contacts
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Experimental results of steady dimples measured in elliptical glass-steel contact under pure sliding conditions are presented. It is found that two dimples connected with a shallower furrow are ...
