| Abstract: | A model with three masses and six degree of freedom for studying the response of bearing-rotor-stator system is presented. The bifurcation and chaos behavior of bearing-rotor-stator with local rubbing are studied by means of numerical stimulation with variations in multiparameters , the bifurcation behavior and chaos motion of bearing-rotor-stator are analyzed in detail. The system of bearingrotor-stator with nonlinear local rub-impact has abundant dynamic behavior. |
