【 摘 要 】

The monitoring of rolling bearing with electrostatic method is a novel technology at present. Few experiments have been investigated with information fusion technique to improve the efficient of monitoring. This paper introduced a new method called moving window local outlier factor (MWLOF) to process electrostatic monitoring signals of rolling bearing under variable operating conditions. In the load and accelerated life tests, the extracted features can reduce the impact and accurately reflect the wear condition of the bearings compared with traditional features. It can detect weak faults earlier and has a better sensitivity and performance degradation trend than conventional techniques, which has a bright future in industrial application.
