Abstract: A sudden increase of vibration amplitude with no forebodingoften results in an abruptbreakdown of a mechanical system. The catastrophe of vibration state of a faulty rotor is a typical non-linear phenomenon，and very difficult to be described and predicted with linear vibration theory. On thebasis of nonlinear vibration and catastrophe theory,the catastrophe of the vibration amplitude of the fauty rotor is described; a way to predict its emergence is developed.
