【Abstract】 Combing fuzzy theory with neural network may improve the technology of mechanical machinery fault diagnlsis. This paper demonstrates the combination of diagnlsis models of single symptom and multi-symptom with neural networks. According to fuzzy diagnosis model, this paper supposes a plastic learning method by adding subnetworks and subjoints. Fuzzy pattern recognition theory directs the samples orgination of neural learning. Based on fuzzy neural network model,a machinery fault diagnlsis system is built and tested in production plant.更多还原
