摘要：

This paper describes the application of a hierarchical neural network to the positioning of crack arrester with the crack propagation analysis. The present method has three steps. Firstly, crack propagation analyses are performed to assemble the data for neural network learning. Secondly, the neural network is learned using the back-propagation method and the assembled data above. Finally, the positioning of crack arrester is done using the learned neural network. The result shows that the proposed method can predict the exact position of crack arrester more than 97% cases.
