Rotor System Evaluation Using Open-Loop Characteristics, as a control system as shown in Fig.?8.1, of which the open-loop characteristics are related to the vibration characteristics: the gain cross-over frequency is an estimate of the natural frequency, and the phase margin is an indicator for the damping ratio. Details of estimation are described below.

Modal Analysis of Multi-Degree-of-Freedom Systems,ould, however, be analyzed as a multi-degree-of-freedom (multi-dof) system where multiple masses are arranged according to the shape of the rotor shafting. The equation of motion for such a system is represented using matrices. Eigenvalue analysis of the multi-dof system gives the natural frequencie

Mode Synthesis and Quasi-modal Method,r have the representation of the original physical coordinates. This chapter discusses methods to reduce the order of the system while preserving the physical coordinates as far as possible. One such method is based on Guyan reduction, in which only the “relatively important” nodes are chosen out of
