Abstract

Abstract: The rotating system of CT machine is simplified into a rigid rotor system. There exist clearances between the stator and the elastic support. The nonlinear vibration is analyzed analytically first. With the numerical method, the bifurcation behaviors and chaos are studied with such paraceters as clearance, eccentric and rotating velocity.

Key words: Bifurcation, Chaos, CT machine, Nonlinear dynamics, Rotating system
