Indentification of multiple fault parameters in rotor bearing coupling systems based on forced response measurments

Abstract

This work focuses in two main facets of the rotor dynamics field the analysis of rotor bearingcoupling system i e the direct problem and the fault detection and diagnosis i e the inverse problem The linear analysis of rotor bearing system is quite mature and now trend is towards the numerical simulation of complicated rotor systems The fault detection and diagnostic is not straight forward since different faults may produce similar vibration signature Frequent faults that appear in r
