Abstract

This paper analyzed the chaotic behaviors and vibration phenomenon of a flexible rotor with different mass and bearing number supported by ultra short aero-lubricated bearing (USAB) system. The hybrid method combined with differential transformation method and finite difference method are proposed and used to calculate gas pressure distribution of USAB system. The results are shown that system exist chaotic motions over the specific ranges, and the maximum Lyapunov exponent is positive as chaos occurred.
