| Abstract: | Taking the advantage of fuzzy mathematics in describing the fuzzy relationship between oil pollution and machine abrasion,the article sets up a mathematic model for fuzzy fault diagnosis.On the basis of fuzzy fault diagnosis for current pollution degree,compressing and restructuring of fault symptom space will greatly reduce the calculation work and improve the efficiency of fault diagnosis. |
