Abstract

Based on the load balance equations of sliding bearing fluid-solid coupling motion

the mechanism of instability in bearing-rotor system was presented.According to the coupling relationship between whirl frequency and nonlinear coupling vibration frequency

a new technology was put forward to perform rotor-bearings system frequency coupling modulation.Through experiments of oil whirl

sub-harmonic resonance and other self-excited vibration

a criterion for rotor-bearing stability and nonlinear dynamics characteristics were presented.Moreover

relevant theoretical and experimental references were provided to achieve effective control of rotor-bearing nonlinear vibration.
