Elastohydrodynamic Lubrication for Line and Point Contacts: Asymptotic and Numerical Approaches describes a coherent asymptotic approach to the analysis of lubrication problems for heavily loaded line and point contacts. This approach leads to unified asymptotic equations for line and point contacts as well as stable numerical algorithms for the solution of these elastohydrodynamic lubrication (EHL) problems. A Unique Approach to Analyzing Lubrication Problems for Heavily Loaded Line and Point Contacts The book presents a robust combination of asymptotic and numerical techniques to solve EHL problems for lightly and heavily loaded line and point contacts. It also proposes a reasonably simple and naturally based regularization approach that produces stable solutions in heavily loaded EHL contacts. The book offers a clear understanding of the processes taking place in heavily loaded line and point EHL contacts as well as of the proper solution structure for EHL problems. It outlines concrete ways to determine important design parameters such as lubrication film thickness and frictional stresses and forces. The book establishes a close link between EHL problems for heavily loaded point and line contacts. Fine Tune Your Methods for Solving Elastohydrodynamic Lubrication Problems In most cases, the equations in the book are derived from first principles. The author describes each of the asymptotic and numerical methods in detail, making it easier for readers to apply them to various problems. The problem solutions are presented in the form of simple analytical formulas, graphs, and tables. Almost all the chapters include exercises that highlight key points and skills. Suitable for engineering and applied mathematics students, this is also a unique resource for researchers and practitioners who want to fine tune their solution methods and design better numerical methods to tackle elastohydrodynamic lubrication problems.

Efficient numerical solution of realistic and, therefore, complex equation systems occupies many researchers in many disciplines. For various reasons, but mainly in order to approximate reality, a very large number of unknowns are needed. Using classical techniques, the solution of such a system of equations would take too long, and so sometimes MultiLevel techniques are used to accelerate convergence. Over the last one and a half decades, the authors have studied the problem of Elastohydrodynamic Lubrication, governed by a complex integro-differential equation. Their work has resulted in a very efficient and stable solver. In this book they describe the different intermediate problems analyzed and solved, and how those ingredients finally come together in the EHL solver. A number of these intermediate problems, such as Hydrodynamic Lubrication and Dry Contact, are useful in their own right. In the Appendix the full codes of the Poisson problem, the Hydrodynamic Lubrication problem, the dry contact solver and the EHL solver are given. These codes are all written in 'C' language, based on the 'ANSI-C' version.

The thirteenth Leeds-Lyon Tribology Symposium was devoted to the topic of Fluid Film Lubrication in celebration of the centenary of the publication of the classical paper by Professor Osborne Reynolds in which he identified the mechanism of hydrodynamic lubrication. These proceedings contain more than seventy papers, written by authors from all over the world, covering the entire spectrum of fluid film lubrication. Of particular interest is the detailed consideration of a wide range of machine elements - bearings, seals, cams, rolling elements, as well as the in-depth, state-of-the-art, analytical contributions.

Das Buch beinhaltet eine strukturierte Sammlung der vollständigen Lösungen aller wesentlichen axialsymmetrischen Kontaktprobleme. Es werden Lösungen für klassische Profile wie die Kugel, den Kegel oder den flachen zylindrischen Stempel angegeben, aber auch für eine Vielzahl weiterer technisch relevanter Formen, z.B. den Kegelstumpf, den Zylinder mit abgerundeten Rändern, die verschlissene Kugel, Profile mit Welligkeit, Hohlzylinder usw. Behandelt werden Normal-, Tangential- und Torsionskontakte -, sowohl adhäsionsfreie als auch adhäsionsbehaftete. Als Medien kommen elastisch isotrope, transversal isotrope, viskoelastische sowie funktionale Gradientenwerkstoffe zur Sprache. Die Lösungen der Kontaktprobleme umfassen neben den Zusammenhängen zwischen den makroskopischen Kraft- und Verschiebungsgrößen sowie der Kontaktkonfiguration auch die Spannungs- und Verschiebungsfelder an der Oberfläche und gegebenenfalls innerhalb des Halbraum-Mediums. Lösungen werden immer mit der jeweils einfachsten zur Verfügung stehenden Methode gewonnen – meistens mit der Methode der Dimensionsreduktion oder Ansätzen zur Rückführung des jeweiligen Kontaktproblems auf das nicht-adhäsive Normalkontaktproblem.Die ZielgruppenDas Buch wendet sich an Berechnungsingenieure in der Industrie wie z.B. Maschinenbau, Reifenindustrie, Automobilindustrie, Polymer- und Elastomerhersteller. Zugleich dient es als Nachschlagewerk in Forschung und Lehre.
