APPLICATION OF MORPHOLOGY FILTER IN THE EARLY FAULT DIAGNOSIS OF ROLLING BEARING ACOUSTIC EMISSION SIGNALS

摘要：

In this paper, the experiments were carried out in the rolling bearing test rig in the lab. The AE signals were collected by the AE sensors. Morphology filter is used to process the AE signals collected from the defective rolling bearing then the fault frequency characteristics are obvious in the frequency spectrum. The morphology filtering method has high efficiency and simple algorithm. It is fit for early and online diagnosis of the rolling bearings.
