Vibration Analysis of Rotors is concerned with the important topic of rotor dynamics. Rotor problems are examined through vibration analysis and emphasis is placed on the analytical aspects. The book is therefore very useful as an advanced course/self-study book on rotor dynamics for readers with a good knowledge of vibration analysis. The text introduces simple rotor systems and gradually progresses to the complex systems, with a description of all analytical solutions for discrete and continuous rotor systems. A useful chapter is devoted to the introduction of lambda matrices, which allow a unified approach to the rotor vibration problems examined later in the book. Vibration Analysis of Rotors is vital reading for graduate-level mechanical engineers, either on rotor dynamic courses or who need a reference text.
