Development of intelligent fault diagnosis

Machinery is an important equipment for the citizen economic construction. It is of great significance to study the fault diagnosis method of machinery. Currently, the key point of rotating machinery fault diagnosis is diagnostic accuracy. According to particulars of fault diagnosis, information fusion technology was analyzed considering information diversity and symptom complex of machinery. The relationships between fault diagnosis and other application technology were explained. The fault signal collecting and processing method, fault diagnosis decision were reviewed. The development of intelligent method of vibration fault diagnosis for machinery has ho predicted.
