| Abstract: | Vibration signals of a machine proved to be non-stationary ones and they usually carry the dynamic information of a machine that is very useful for fault diagnosis. The local wave method is a very good tool for signal identification. In this paper,a new and efficient fault diagnosis system based on the local wave method was developed,and a RBF network was introduced. Accordingly,a new local wave fault diagnosis approach was also developed. The proposed fault diagnosis approach was tested on diesel engine piston-liner wear estimation and the results showed that the system was effective. |
