Analysis of vibration responses of defective rolling bearings using Blind Source Serparation
نویسنده
چکیده
Separating vibration signals generated by defective rolling bearings is of major importance for rotating machinery health monitoring, since rolling bearings of the same type are quite frequently encountered in the industrial environment, especially in large machines, critical in the production process. For this reason, Blind Source Separation (BSS) is considered for application on vibration signals, which may include characteristic simulated defective bearing responses under different types of bearing faults. It is demonstrated that the BSS method, properly implemented, is quite able to decompose the measured signal into a number of independent components, each one corresponding to the vibration induced by an individual bearing. Key-words: Blind Source Separation, Independent Component Analysis, bearings,vibration analysis
