| Abstract: | Rotor-stator rub is a common fault difficult to diagnose in rotating machinery. The vibration characteristics of a Jeffcott rotor with linear bearings, nonlinear stiffness shaft and rotor-stator rub are investigated theoretically. Some nonlinear dynamic phenomena of the rotor investigated, including coexistence of attractors, quasi-periodic vibrations, subharmonic vibrations and bifurcations, are revealed. The conclusions of the paper are conducive to the accurate diagnosis of rub faults in rotating machinery.6figs.,9refs. |
