About the Book

This book is written as an introduction to rotor-bearing dynamics for practicing engineers and students who are involved in rotordynamics and bearing design. The goal of this book is to provide a step-by-step approach to the understanding of fundamentals of rotor-bearing dynamics by using DyRoBeS©. Therefore, the emphasis of this book is on the basic principals, phenomena, modeling, and interpretation of the results. Numerous examples, from a single-degree-of-freedom system to complicated industrial rotating machinery, are employed throughout this book to illustrate these fundamental dynamic behaviors. The concepts in the text are reinforced by parametric studies and numerous illustrative examples and figures.

The book begins with a brief discussion of the mathematical modeling of physical dynamic systems and an overview of the basic vibration concepts in Chapter 1. The coordinate systems and the kinematics of the rotor motion are presented in Chapter 2. A simple two-degrees-of-freedom rotor system, the Laval-Jeffcott rotor model, is utilized in Chapter 3 to demonstrate many important phenomena in rotordynamics. This simple 2DOF model provides many valuable physical insights into more practical and complicated systems. Chapter 4 discusses the rotating disk equations and rigid rotor dynamics. Chapter 5 covers the finite element formulation for a rotating shaft element. Chapter 6 deals with various types of bearings, dampers, seals and other interconnection components. All the reaction forces from these components are non-linear in nature. The concept of linearization around the static equilibrium is discussed. Chapter 7 summarizes the lateral vibration study with several practical examples. Various solution techniques and interpretation of the results are discussed. Chapter 8 is devoted to the important subject of torsional vibration. Finally, a brief description of the balancing method, influence coefficient method is presented in Chapter 9.

He is a registered Professional Engineer in the State of Illinois. Dr. Chen was awarded the H.H. Jeffcott Award for outstanding paper on rotating machinery. He made significant contributions in the area of rotating machinery as a practical industrial engineer and outstanding researcher. His achievements have been both analytical and design-oriented and have spanned a broad spectrum of topics within the general area of rotating machinery. Dr. Chen is clearly a versatile and prolific researcher and is well respected in the rotordynamics communities, both academic and industrial.

Edgar J. Gunter, Jr. Ph.D., Fellow ASME, is the founder of RODYN Vibration Analysis, Inc. He has worked in the field of vibrations of rotor machinery and fluid bearings for over 40 years and written over 150 technical papers and reports on various aspects of the dynamics of rotating machinery, fluid film bearings and balancing. Dr. Gunter is now a professor emeritus, after teaching for 34 years in the Department of Mechanical, Aerospace and Nuclear Engineering at the University of Virginia. He has worked with industry and government on various rotor dynamic and vibration problems. He has also consulted with NASA and participated in hands-on work on the space shuttle program in it's early days. NASA engineers utilize DyRoBeS© software extensively, and Dr. Gunter has presented numerous on-site training courses at NASA on the use of both the rotor dynamics and bearing components of the software.
