摘要：

This study proposes the method of remaining useful life estimation based on accelerated life test. To estimate the remaining useful life of the bearing, the confidence of accelerated life test needs to be validated. First, the properties of bearing depend on bearing state are analyzed. The accelerated life test conditions are established following bearing state. In addition, the fault condition is defined by the acoustic noise changes. Finally, the results of normal condition test and accelerated life test are compared to validate the confidence of accelerated life test. By validated accelerated life test, the remaining useful life and changes by bearing degradation can be investigated easily. In addition, accumulating historical data of degraded bearings can be facilitated.
