In this updated and revised second edition, the authors present asystematic and practical approach to the analytical and numericalaspects of the prediction of rotordynamics behaviour. The influenceof bending is a main theme of the book, although the effects oftorsion are also considered. The use of finite element techniquesand the characteristics of rotor elements are introduced. The bookgoes on to consider simple models showing basic phenomena which arethen linked to industrial applications such as turbocompressors,high pressure centrifugal compressors, and steam and air turbines.
