Abstract

Identifying the classification of rotor systems is prerequisite for clear determination of the fault analysis and precise parameter identification for the rotor system, through which operating conditions may be rationally ascertained. For this purpose, the simple creative technique associated with the directional frequency spectrum (dFS) is proposed by using an inherent property of rotor system. Also the features and the dynamic characteristics of the rotor systems relating to the harmonic modes are investigated.
