| Abstract: | Mechanical and numerical model of a dual-disc over-hung rotor-bearing system were built respectively. By using the experimental instruments for rubbing fault, the influences of nonlinear characteristics of rotor system with rubbing fault, such as eccentricity, clearance, and rubbing on mid-disc were studied. And further analyses were carried out on dynamic characteristics of rotor system with rubbing on mid-disc and rotor system with rubbing on over-hung disc. The simulation results meet the experimental ones well. The study may do favor to the safe and stable running of the practical rotating machinery. |
