序
However, most books on tribology mainly introduce theories or calculation methods oflubrication. They rarely give and discuss numerical calculation programs.
Not only is this inconvenient for research or the production of practical lubrication,but also many similar programming tasks have to be carried out repeatedly. Furthermore, because of the limitations of lubrication theory, some numerical calculation programs may give mistaken solutions, leading to wrong conclusions.
This book is different from previous theoretical books or monographs on lubrica-tion; it mainly introduces the numerical calculation programs of lubrication, This is the main feature of the book. Some of the programs have been used for many years in lubrication calculations and research by the author.
Due to the complexity oflubrication problems, the book mainly focuses on how to numerically solve the Reynolds equation, energy equation, elastic deformation equation and their combinations. The analyzed lubrication problems include line, surface and point contacts, which correspond to thrust bearings, journal bearings and rolling contact bearings. Furthermore, the working conditions include incompressible, compressible, nonthermal, thermal, isoviscosity, variable viscosity, Newtonian fluid, non-Newtonian fluid (only grease), rigid and elastic deformation situations.
The book is divided into four parts, covering 24 chapters:
The first part (Chapters 1-9) is about the solution ofthe Reynolds equation, which is the basic technique for the numerical analysis of lubrication. The contents include the boundary and connection conditions of the Reynolds equation, discretizing the Reynolds equation, numerical methods and programs of slider lubrication, numerical methods and programs of journal bearing lubrication, numerical methods and programs of dynamic bearing lubrication, numerical methods and programs of gas lubrication (especial magnetic hard disk/head) and so on.ln this part, we also discuss the theology oflubricants. As an example, grease lubrication is discussed, which is a kind of non-Newtonian fluid.
The second part of the book (Chapters 10 and 11) is on temperature calculation.
