Study on Fault Diagnosis of Gear Wearing Based on Non-stationary Acoustic Signal

摘要：

Because of the restriction of self-propelled gun full-scale test, and because the traditional vibration test cant be used for non-contact, nondisassembly and nondestructive test. A method that utilizes the non-stationary acoustic signal for gearbox fault diagnosis was introduced. In order to process the non-stationary signals such as speed up signals effectively, the order tracking technique were presented. Combined the cepstrum analysis to conquer the disadvantage of traditional FFT when processing non-stationary signal. Compared to the vibration signals, the gearbox gear wearing fault experiment and data analyzing showed its feasibility and superiority.
