A Fault Diagnosis Method for Automotive Engine Bearings Based on Wavelet Packet Analysis
This article proposes the application of wavelet packet in the fault diagnosis of automotive engine bearings.The early damage monitoring technology of structural materials based on wavelet packet is relatively simple and has the advantage of being more sensitive to early fault damage.Based on the analysis of the fault transmission signals of failure and destruction,wavelet packet decomposition technology is used to effectively extract the vibration characteristic parame-ters of automotive engine bearing faults,and it is applied to the fault diagnosis method of automotive engine bearings.Through experimental verification,efficient diagnosis of automotive engine bearing faults is achieved.
