Fault Early Diagnosis of Rolling Element Bearing Based on Local Wave Method and Cyclostationarity Analysis

摘要：

Cyclostationarity analysis is a specific non-stationary process characterized by the periodical variation of the statistical moments. It has been widely used in the fault diagnosis of gears, rolling element bearings, et al. A new method for fault early diagnosis of rolling element bearing based local wave denoise and cyclostatinarity method presented. Application indicates that this method more effective and accurate in extracting fault features from signals.1
