Abstract：The response of a rotor supported on ball bearings which considering nonlinearity such as surface waviness, internal radial clearance and Hertzian contact force is analyzed and the result is presented in the form of bifurcation diagram, power spectra and Poincaré map. The effect of maximum amplitude of waviness and speed on the dynamic of the rotor response is mainly studied and the characteristic frequency of surface waviness is analyzed. G-P method is used to calculate the correlation dimension at different maximum amplitudes. The result shows that the correlation dimension will increase with the addition of amplitude of the waviness when the system in chaos and it’s implied that the correlation dimension can be usefully applied to the diagnosis and quantitative identification of the fault of waviness.
