Analysis of Rotor Systems Volume 1, 2nd Edition


Analysis of Rotor Systems: Volume 1, 2nd Edition
English | 2026 | ISBN: 1041103557 | 704 pages | True PDF,EPUB | 82.90 MB
The first volume of the second edition of Rotor Systems covers the analysis of simple rotors, including bearing and gyroscopic effects, with the help of simple rotor‑bearing models. It is biased toward the finite element method analysis for complex rotors, both for torsional and transverse vibrations, including the transfer matrix method. In torsional vibration geared-rotor and branched system is also covered. The torsional and transverse vibration analysis covers the free and forced vibration analyses. Eigenvalue analysis helps in developing Campbell diagram for obtaining critical speeds. Unbalance response analysis helps in finding rotor response with rotor speed.Key Features:Covers rotor analysis from simple single degree of freedom to multi‑degree of freedom with lots of solved examplesIllustrates bearing and seals theory with a perspective on rotor dynamicsDiscusses the finite element method and transfer matrix methods for torsional and transverse vibration analysisIncludes elemental equations derived from the Euler-Bernoulli beam model, Rayleigh's beam model, and Timoshenko beam modelExplores the Campbell diagram for forward and backward critical speed analysis, also Bode Description for unbalance response analysis with rotor speed.This book is aimed at senior undergraduate/graduate students in mechanical engineering, rotor dynamics, rotating machinery/turbomachinery, and related fields.
