The rolling bearing fault detection test-bed is established for the rolling bearing fault diagnosis,which is based on the acoustic emission sensors,PCI-2 AE data acquisition card and AEwin software systems.The AE signals are processed by energy analytical method for preliminary fault diagnosis.The autocorrelation processed AE signals are transformed by FFT to obtain the frequency domain signals,and the approximately principle in the fuzzy recognition method is adopted;the membership functions and closeness ...
