Synopsis
It is increasingly necessary in the design of rotating machinery to predict accurately the dynamic behaviour of rotors in bending and in torsion. The influence of bending is the main subject of this book, with one whole chapter devoted to the influence of torsion. The book contains systematically obtained equations, including Lagrange's equations and the Rayleigh-Ritz method. It is aimed at engineers, and graduates and undergraduates concerned with predictions in rotordynamics. It attempts to be accessible and practical, but some previous knowledge of rigid body mechanics, strength of materials, matrix calculations, differential equations and mechanical vibrations is required.

Quatrième de couverture
In this updated and revised second edition, the authors present a systematic and practical approach to the analytical and numerical aspects of the prediction of rotordynamics behaviour. The influence of bending is a main theme of the book, although the effects of torsion are also considered. The use of finite element techniques and the characteristics of rotor elements are introduced. The book goes on to consider simple models showing basic phenomena which are then linked to industrial applications such as turbocompressors, high pressure centrifugal compressors, and steam and air turbines. Key features include:
- The inclusion of a computer program available free of charge on the Internet
- The development of a simple model of co–axial multirotors
- New industrial applications and 1995 API specifications
