Bearing Dynamic Coefficients in Rotordynamics - (Wiley-Asme Press) by Lukasz Brenkacz (Hardcover)

About the Book

"The analysis of dynamic properties of rotating machinery has for many years been the subject of numerous research works carried out in many scientific centers. From modern day rotating machinery it is required to work with increasingly difficult operating parameters while maintaining a light and compact design. Increased efficiency, reliability and precision are also required. Rotating machinery with hydrodynamic bearings are used in many sectors of the economy, e.g. energy, transport, aviation and military. Very often they are a key element of large technical objects. In steam turbines used for energy conversion, one of the key components are hydrodynamic plain bearings. These machines are referred to as "critical machinery", i.e. they are required to be immensely reliable. Unplanned downtime due to poor technical condition leads to significant financial losses. They are therefore monitored and thoroughly analyzed."--

Book Synopsis

A guide to bearing dynamic coefficients in rotordynamics that includes various computation methods

Bearing Dynamic Coefficients in Rotordynamics delivers an authoritative guide to the fundamentals of bearing and bearing dynamic coefficients containing various computation methods. Three of the most popular and state-of-the-art methods of determining coefficients are discussed in detail. The computation methods covered include an experimental linear method created by the author, and numerical linear and nonlinear methods using the finite element method. The author--a renowned expert on the topic--presents the results and discusses the limitations of the various methods.

Accessibly written, the book provides a clear analysis of the fundamental phenomena in rotor dynamics and includes many illustrations from numerical analysis and the results of the experimental research. Filled with practical examples, the book also includes a companion website hosting code used to calculate the dynamic coefficients of journal bearings. This important book:

• Covers examples of different computation methods, presents results, and discusses limitations of each
• Reviews the fundamentals of bearing and bearing dynamic coefficients
• Includes illustrations from the numerical analysis and results of the experimental research
• Offers myriad practical examples and a companion website

Written for researchers and practitioners working in rotordynamics, Bearing Dynamic Coefficients in Rotordynamics will also earn a place in the libraries of graduate students in mechanical and aerospace engineering who seek a comprehensive treatment of the foundations of this subject.
