【Abstract】 Fuzzy rules of bearing fault diagnosis are summarized and maped into fuzzy neural network, which improves intelligence of bearing diagnosis. Part layer learning algorithm is presented. Meanwhile, parameter learning algorithm of the membership function is developed. Both of them improve diagnostic rules as well as learning properties. As to bearing fault, satisfied diagnosis results are obtained by means of the developed diagnostic system.更多还原
