THE FAULT DIAGNOSIS BASED ON BP NEURAL NETWORK

This article discuss the structure and learning arithmetic of BP neural network as well as the principle and process of the application to fault diagnosis.The operational principle of tractor gear--box is analysised. BP neural network are applicated to the fault diagnosis of this Engineering utilizing the merit of BP neural network. This test showed that the fault diagnosis based on neural network comes to become mature.
