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:
CT machine
Rotating system Nonlinear dynamics Bifurcation Chaos
