This book applies vibration engineering to turbomachinery, covering installation, maintenance and operation. With a practical approach based on clear theoretical principles and formulas, the book is an essential how-to guide for all professional engineers dealing with vibration issues within turbomachinery. Vibration problems in turbines, large fans, blowers, and other rotating machines are common issues within turbomachinery. Applicable to industries such as oil and gas mining, cement, pharmaceutical and naval engineering, the ability to predict vibration based on frequency spectrum patterns is essential for many professional engineers. In this book, the theory behind vibration is clearly detailed, providing an easy to follow methodology through which to calculate vibration propagation. Describing lateral and torsional vibration and how this impacts turbine shaft integrity, the book uses mechanics of materials theory and formulas alongside the matrix method to provide clear solutions to vibration problems. Additionally, it describes how to carry out a risk assessment of vibration fatigue. Other topics covered include vibration control techniques, the design of passive and active absorbers and rigid, non-rigid and Z foundations. The book will be of interest to professionals working with turbomachinery, naval engineering corps and those working on ISO standards 10816 and 13374. It will also aid mechanical engineering students working on vibration and machine design.

About the Author :
Ernesto Novillo has a strong academic background and field experience in power
plants, cement industry, oil fields and naval ship propulsion, where vibration
problems are significant. A former Naval officer, he earned two university engineering
degrees: Electrical-Electronics (Summa Cum Laude) and Mechanical.
Working for General Electric, he delivered large energy engineering projects to
many countries in Asia, Europe, and America throughout his long professional
career. He was a university professor of Automatic Control Systems and Oil
Engineering. His experience encompasses living in several countries, where he
assumed important management positions. He has published books about relativity
science and turbine engineering. In this book, Ernesto combines vibration
theory with his valuable experience in land and marine machinery and automatic
control systems.
