Abstract

With the QPMZ - II type gear box as experimental object, according to the failure mechanism and vibration characteristics under actual condition of the gear box, the vibration signals are decomposed into components at different frequency bands and time period by wavelet transform, so that the interference signals and the desired signals are located in different frequency bands. The wavelet coefficient corresponded by interference signals is set to zero, reconstruct the signals, then the signals are obtained after the noise reduction. Analysis the envelope power spectrum can analysis the diagnose failure effectively.
