Fault Diagnosis of Motor Bearing Equipment Based on Sound Signal

:This paper introduced the practical value of artificial neural network in fault diagnosis field, respectively, applied the BP network, ELMAN network, RBF neural networks insulating oil fault diagnosis. Simulation results show that, in the transformer ...

BP neural network is easily trapped into the local minimum during the training process, which results that it can't get the optimal solution, even misjudging in device fault diagnosis. Directing to the above problems, a Hopfield-BP neural network fault ...

The paper combined the advantage of Particle Swarm Optimization algorithm (PSO), the global optimizing ability of Hopfield Neural Network, and the teacher supervising features of BP neural network to construct a new equipment fault diagnosis method with ...
