Abstract

This paper reports on the application of correlation dimension D2,largest Lyapunov exponent ʎ1 and maximum approximate entropy ApEtl max to diagnose the severity of rotor-to-stator rub in rotating machinery. The method of time delay was employed to reconstruct the vibration signal obtained from numerical simulation of a Jeffcott rotor subjected to rotor-to-stator rub. Numerical results showed clear correlation between the increase of rub severity with the invariant quantities,D2,ʎ1 and ApEtl max,investigated in this work.
