The Periodical Trend Extraction from Non-stationary Time-series with Cyclostationary Approach and Machinery Fault Diagnosis
Longxing Yang · Machine Tool & Hydraulics · 2006
An approach of machinery fault diagnosis and analysis method was presented on the basis of the introduction of periodical trend extraction from non-stationary time-series model.The approach extracts the periodical trend from non-stationary time-series with cyclostationary analysis,then sets up stationary time-series model to monitor machinery faults.The simulation and an example were given to show the approach availability.
