Rotating parts are among the most common elements in modern mechanical systems and often become the main source of problematic vibrations in machinery. This volume offers wide-ranging coverage of fundamental rotordynamics in order to provide engineers with the necessary knowledge to eliminate various vibration problems. Authors Yamamoto and Ishida provide classification of rotating shaft systems and general coverage of key ideas common to all branches of rotordynamics, such as critical speed, gyroscopic movement, whirling motion, and frequency diagrams. They also provide state-of-the art analysis of dynamical problems not treated in most other books on the subject, such as nonlinear rotordynamics, self-excited vibration, nonstationary vibration, and flow-induced oscillations. Nonlinear resonances are discussed in detail, as well as methods for shaft stability and various theoretical derivations and computational methods for analyzing rotors to determine and correct vibrations. Linear and Nonlinear Rotordynamics is a professional engineer's complete resource for dealing with vibration in rotordynamical systems. This 2nd edition is completed by two topics of high importance: - A new chapter on vibration Suppression presents various methods and is a helpful guidance for professional engineers. - A new chapter on Magnetic Bearings. As they support the highest speeds of any kind of bearings, they are in service in such industrial applications as electric power generation, petroleum refining, machine tool operation and natural gas pipelines. This new chapter provides fundamental knowlegde and enables the reader to realize simple magnetic bearings by hands in laboratory.
