| 摘 要： | Most of the research work on bearing-rotor systems usually simplifies the supporting bearing as a spring or damp system, and ignores that the resonance responses involve obvious differences when the same rotor system is supported by varying types of bearings. Aiming at the resonance responses of coast down running tests of the rotor system, we employed two different bearings in experiments: One is the fluid film journal bearing, and the other is the rolling element bearing. The experimental results obtained with the above bearings are compared. The resonance test Bode plots and orbit shapes of the rotor shaft are established. Also, summarized under resonance are the dynamic characteristics and regularities of the two types of bearing-rotor systems. The natural frequency and resonance mode of the same rotor system will change thoroughly with the type of supporting bearings. The results are helpful for system modeling, security running, dynamic design, the study of dynamic characteristics, and the fault diagnose of bearing-rotor systems.
