| Abstract: | The rotor-bearing system with nonlinear rigidity is studied using modern theory of nonlinear dynamics. The motion equation of nonlinear rotor-bearing system is established and the frequency responding equation is obtained by multiple-scales method. The effect of different parameters on vibration responding curves are analyzed. It is indicated by experiment results that there are some characteristic phenomenon on nonlinear vibration curves, such as rounding, bouncing and lagging. It is the basis of fault diagnosis study for rotor-bearing system. |
