Abstract

Abstract

Dynamic characteristics of turbine magnetic bearing system by excitation test are studied in this paper.The method can be useful for prediction of critical speeds,stiffness and damping of the system,before it goes into operation.On the other hand,excitation test shows that adjustment of control parameters has less influence on some critical speeds.
