Abstract

This paper presents a study on the stability of a viscous liquid-filled rotor supported by a pair of magnetic bearings which are placed at both ends of the shaft connected to the rotor. The liquid is regarded as an incompressible one. The surface tension of the liquid and the gravitational acceleration are assumed to be negligible. In addition to the translational mode, the tilting mode is also taken into account here. The breakdown of the system consists of three parts: the motion of the liquid, the motion of the rotor and the control system of the magnetic bearings. The effects of various parameters on the stability of the rotor system, for example, the viscosity of the liquid, the liquid filling ratio, the position of the rotor, and the control parameters for magnetic bearings are studied theoretically.
