Vibration Analysis of Gearbox Fault Diagnosis using DWT and Statistical Features

Modern Vibration Signal Processing Techniques for Vehicle Gearbox Fault Diagnosis

This paper presents modern vibration signalprocessing techniques for vehicle gearbox fault diagnosis, via the wavelet analysis and the Squared Envelope (SE) technique. The wavelet analysis is regarded as a powerful tool for the detection of sudden changes in non-stationary signals. The Squared Envelope (SE) technique has been extensively used for rolling bearing diagnostics. In the present work...

Cepstrum Analysis and Gearbox Fault Diagnosis

Misalignment Diagnosis of a Planetary Gearbox Based on Vibration Analysis

As a critical power transmission system, planetary gearbox is widely used in many industrial important machines such as wind turbines, aircraft turbine engines, helicopters. Early fault detection and diagnosis of the gearbox will help to prevent unexpected breakdowns of this important equipment. Misalignment is one of the major operating problems in the planetary gearbox which may be caused by ...

Vehicle Gearbox Fault Diagnosis Based On Cepstrum Analysis

Research on damage of gears and gear pairs using vibration signals remains very attractive, because vibration signals from a gear pair are complex in nature and not easy to interpret. Predicting gear pair defects by analyzing changes in vibration signal of gears pairs in operation is a very reliable method. Therefore, a suitable vibration signal processing technique is necessary to extract defe...
