FUZZY DIAGNOSIS METHOD IN MACHINERY CONDITION MONITORING AND FAILURE DIAGNOSIS

The method of fuzzy diagnosis is applied to machinery condition monitoring and diagnosis systems. The fuzzy systems can cope not only with the transitional stage between perfect and defect states of a machine or their elements, but also with multifailures. Two different kinds of imprecision during failure diagnosis--namely, randomness and fuzziness--are considered in the diagnostic system. As an example of the application of the fuzzy system, the failure diagnosis problem in rolling element bearings is discussed. The approach to fuzzy diagnosis might also be used to construct inference rules for expert systems used in mechanical failure diagnosis.
