| Abstract: | This paper is concerned with designing fault finding expert system and its application in centrifugal machines. Vibration signals are collected by sensors. Vibration images are identified by numerical computation. According to the different vibration frequencies the characteristics of many kinds of fault can be shown. Through the fault tree analysis of the system, an expert system for fault finding is established. The application on DRJ 460 centrifuge is shown in detail. |
