... faults respectively, it has been shown that the gear fault diagnosis approach based on IMF AR model and SVM can be applied to classify the gear working conditions and fault patterns effectively and accurately even ... AR model can only be applied to stationary signals, while the gear fault vibration signals always display nonstationary behavior. To target this pro...

... (AE) events can serve as a source of information for locating the damage, particularly as caused by the initiation and propagation of microcracks [1–3]. The spatial distribution of AE locations ... noise. Therefore, an AE system that automatically “learns” crucial patterns from the total AE data, as well as particular P-wave arrivals, may provide clues for distinguishing between real...
