Abstract

The detection of structural defects in a ball bearing using an embedded piezoceramic load sensor and the discrete wavelet transform is presented. A model to predict the output of the embedded sensor was developed and experimentally verified. A mother wavelet was developed specifically for analyzing the response of the bearing and embedded load sensor. This wavelet was found to produce a more descriptive decomposition of the sensor signal than a standard Daubechies wavelet. Furthermore, the relationship between a bearing misalignment and the resulting load variation was established.
