An Efficient Solution Procedure for Elastohydrodynamic Contact Problems Considering Structural Dynamics by Jan Henrik Schmidt Pdf

This work presents an efficient solution procedure for the elastohydrodynamic (EHD) contact problem considering structural dynamics. The contact bodies are modeled using reduced finite element models. Singly diagonal implicit Runge-Kutta (SDIRK) methods are used for adaptive time integration. The structural model is coupled with the nonlinear Reynolds Equation using a monolithic coupling approach. Finally, a reduced order model of the complete nonlinear coupled problem is constructed.

Elasto-Hydrodynamic Lubrication by D. Dowson,G. R. Higginson Pdf

Elasto-Hydrodynamic Lubrication deals with the mechanism of elasto-hydrodynamic lubrication, that is, the lubrication regime in operation over the small areas where machine components are in nominal point or line contact. The lubrication of rigid contacts is discussed, along with the effects of high pressure on the lubricant and bounding solids. The governing equations for the solution of elasto-hydrodynamic problems are presented. Comprised of 13 chapters, this volume begins with an overview of elasto-hydrodynamic lubrication and representation of contacts by cylinders, followed by a discussion on equations relevant to lubrication, including the Reynolds equation. The reader is then introduced to lubrication of rigid cylinders; the importance of film thickness in highly loaded rigid contacts; the elasticity of solids in contact; and the theory of elasto-hydrodynamic lubrication. Subsequent chapters focus on apparatus and measurements of film thickness and film shape; friction and viscosity; and lubrication of gears and roller bearings. This book will be of interest to tribologists.

Developments in Numerical and Experimental Methods Applied to Tribology by D. Dowson,C. M. Taylor,M. Godet Pdf

Developments in Numerical and Experimental Methods Applied to Tribology contains the proceedings of the 10th Leeds-Lyon Symposium on Tribology held at the Institut National des Sciences Appliquées in Lyon, France, on September 6-9, 1983. The papers explore developments in numerical and experimental methods used in tribology and cover topics ranging from ferrography and rheology to bearings and bearing dynamics, hydrodynamics, contact phenomena, and plasticity. The papers are organized into 13 sessions. The first two papers examine the use of ferrography in the analysis of non-ferrous particles as well as some of the methods of obtaining approximate numerical solutions to boundary-value problems that arise in elastohydrodynamic lubrication. The next session is concerned with rheology and contains papers that describe numerical solutions for power law fluids as applied to slider bearings; grease lubricated finite length bearings; and the use of the ball bearing as rheological test device. The papers that follow discuss bearings and their dynamics, oil films on lubricated surfaces, hydrodynamic lubrication, and finite element analysis of transient elastohydrodynamic lubrication. The final session considers plastic deformation, two body abrasion processes, and micropitting and asperity deformation. This monograph will appeal to tribologists.

Elastohydrodynamics by Ramsey Gohar Pdf

Elastohydrodynamic lubrication (EHL) is a difficult topic, embracing several disciplines, which can cause many problems for engineers and scientists. This up-to-date volume explains the subject both theoretically and experimentally. Moreover, with a refreshing approach and using several novel techniques of application, it provides lucid coverage of new and important findings. Here, in one volume, are the results of much research over the last forty years. The author's clear explanation of the theory of EHL is authoritatively applied to a wide range of related topics, with physical explanations wherever possible. Many of the experimental techniques described were carried out at the Imperial College Lubrication Laboratory, where the application of interferometry (a means of measuring the EHL film thickness) was pioneered.
