Stability Analysis of a Flexible Bladed-Rotor [PDF]
Key Engineering Materials, 2005 In any high-performance turbo-machinery, instability and damage are commonly occurring problems. The aim of this paper is to present a stability analysis of a fully-bladed flexible rotor. The flexural vibrations of the blades as well as those of the shaft are considered; the energetic approach used includes the effect of the rotational inertia.

Bulletin of JSME, 1977 Unbalanced vibration of a flexible rotor supported on two bearings is analysed in this paper for the case of flexible support with viscous damping. The analytical solution is obtained by using the concept of "forced mode", which makes the vibration phenomena for the system in consideration more understandable than before.
