In high-speed operation, the rotor produces vibration signal, which can comprehensively reflect the working condition of rotating machinery. Taking the high-speed rotor assembly as the research object, this paper measured vibration signal data with the self - research acquisition module. Through on-line monitoring of rotor vibration signal, the fault of rotor can be judged accurately and the fault causes can be quickly found. The Analysis methods such as auto-power spectrum, vibration severity and orbit of shaft centerline are used in experiment. Experiment shows that the system can diagnose the typical fault of rotor assembly accurately, which guarantees the safe operation of rotating machinery.
