| Abstract: | Fuzzy pattern identification method is proposed to solve problems arising in re-analysing frequency spectrum of engineering vibration signals.Take the spectrum analysis of vibration causes of roller bearing as an example,the distribution pattern for frequency of spec- trum peak values,the determination of fuzzy subsets and membership function together with the identification procedure of overall judgement method are introduced.In addition,computational result is provided. |

| Keywords: | frequency spectrum fuzzy pattern identification fuzzy subset membership function. |
