XIE Zhen-yu, XU Long-xiang, LI Ying, et al. Analysis of Radial Dynamic Characteristics of Magnetic Bearing System by Excitation Test[J]. 2004, 19(1).DOI:
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.
