| Abstract: | The method and the theory of fault diagnosis based on the radial basis function neural network are studied.The feature vectors are established by means of wavelet packet,and then recognition of fault pattern of rolling bearing was presented using radial basis function neural network.The experimental result shows that the system can not only detect the fault of bearing but also can recognize inner or outer rings fault pattern correctly.The results are of great significance for engineering application. |
