Book Numerical Calculation of Lubrication

Download or read book Numerical Calculation of Lubrication written by Ping Huang and published by John Wiley & Sons. This book was released on 2013-07-19 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing on basic lubrication problems this book offers specific engineering applications. The book introduces methods and programs for the most important lubrication problems and their solutions. It is divided into four parts. The first part is about the general solving methods of the Reynolds equation, including solutions of Reynolds equations with different conditions and their discrete forms, such as a steady-state incompressible slider, journal bearing, dynamic bearing, gas bearing and grease lubrication. The second part gives the ‘energy equation solution’. The third part introduces methods and programs for elasto-hydrodynamic lurbication, which links the Reynolds equation with the elastic deformation equation. The final part presents application lubrication programs used in engineering. Provides numerical solution methodologies including appropriate software for the hydrodynamic and elasto-hydrodynamic lubrication of bearings Offers a clear introduction and orientation to all major engineering lubrication problems and their solutions Presents numerical programs for specific applications in engineering, with special topics including grease-lubricated bearings and gas bearings Equips those working in tribology and those new to the topic with the fundamental tools of calculation Downloadable programs are available at the companion website With an emphasis on clear explanations, the text offers a thorough understanding of the numerical calculation of lubrication for graduate students on tribology and engineering mechanics courses, with more detailed materials suitable for engineers. This is an accessible reference for senior undergraduate students of tribology and researchers in thin-film fluid mechanics.

Book Multi Level Methods in Lubrication

Download or read book Multi Level Methods in Lubrication written by C.H. Venner and published by Elsevier. This book was released on 2000-07-21 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book A Full system Finite Element Approach to Elastohydrodynamic Lubrication Problems

Download or read book A Full system Finite Element Approach to Elastohydrodynamic Lubrication Problems written by Wassim Habchi and published by . This book was released on 2008 with total page 153 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, a full-system finite element approach to elastohydrodynamic (EHD) lubrication problems is introduced. EHD lubrication is a full-film regime where the pressure generated in the conjunction is high enough to induce a significant elastic deformation of the contacting bodies. Hence, it involves a strong coupling between hydrodynamic and elastic effects. The non-linear system formed by the Reynolds', linear elasticity and load balance equations is solved using a fully-coupled Newton-Raphson procedure. This approach provides outstanding convergence rates when compared with the semi-system one. A penalty method is used to handle the cavitation problem that arises at the outlet of the contact. Appropriate stabilized formulations are used to extend the solution to the case of highly loaded contacts. The resolution process is then extended to account for non-Newtonian behaviour of the lubricant and for thermal effects. The developed model is used to study the behaviour of EHD contacts lubricated with Ultra-Low-Viscosity Fluids. The use of such fluids as lubricants provides two main advantages: first, the frictional energy dissipation in the contact is reduced and second, in machines that work with a low viscosity operational fluid and a lubricant, the former can be used to fulfil both functions and thus the design and maintenance of such machines would become easier and their performance would be improved.

Book excerpt: This volume represents the latest issue of a collection of Proceedings each dealing with a different topic in Tribology. This volume contains the Proceedings from the 23rd Leeds-Lyon Symposium which addressed the topic of Elastohydrodynamics and was attended by many international experts in the field. The Keynote Address was presented by Professor Stathis Ioannides on the subject of "Tribology in Rolling Element Bearings" and was followed by fifteen other sessions covering a wide variety of general areas from "Experimental" to "Lubricant Properties". In addition, nine other invited technical papers were presented to support the sessions.

Book Elasto Hydrodynamic Lubrication

Download or read book Elasto Hydrodynamic Lubrication written by D. Dowson and published by Elsevier. This book was released on 2014-07-18 with total page 254 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
