Abstract: According to the spreading features of mechanical vibration fault, five kinds of Petri net models of fault diagnosis and the corresponding algorithm are proposed. The software engineering is approached to analyze, design and implement the system of mechanical vibration fault diagnosis. Practice proves that this method reduces the failure diagnosis rate and missed diagnosis rate. The difficult problem of fault diagnosis and prediction for mechanical vibration under complex environment is solved.

Key words: mechanical vibration, fault diagnosis, Petri net model, software engineering
