Abstract

Abstract

Dynamic characteristics of turbine expender supported by magnetic bearings are studied in this paper.The relationships among innate frequency,stiffness and damping,and control parameters are discussed.It has been found that adjustment of control parameters has less influence on the first bending critical speed.On the other hand,little damping by control parameters will cause collision easily between the rotor and bearings.
