| Abstract: | The model was founded for ferromagnetism items, according to the study of the MMM testing and faulty diagnosis method. The MMM testing and faulty diagnosis system was designed. The input singal of sensors was proceeded with wavelet analyss for eliminating noise disturbing. The on-line or off-line testing and diagnosis can be carried out to judge the stress concentration zone and find the position of the stress concentrated line. |
