Abstract: The artificial neural network of the fault diagnosis of steam machinery with genetic algorithm is established. The neural network with some fault samples of steam machinery is trained and the neural network model is applied to identify the samples for identify. The result indicates that the method is efficiency in the fault diagnosis of steam machinery.
