Abstract :
Motor´s abnormal vibration signal includes its fault information, effective testing and analysis of its vibration signal is the key to realize motor fault diagnosis. Vibration testing and analysis system was put up to realize the acquisition, display, analysis, storage and replay of vibration signal by using NI-WLS9234 Data Acquisition Card in this paper. Call the analysis function of wavelet in MATLAB to realize vibration signal combined time-frequency analysis by MATLAB Script node in Lab VIEW. The experimental results show that this system has the advantages of convenient operation, high reliability, complete function and good expansibility by using the designed system in three-phase induction motor rotor unbalance fault diagnosis.
