Research on Acoustic Emission Monitoring System of a Certain Plan Fatigue Test Based on Neural Network

摘要：

This paper has studied the acoustic emission (AE)monitoring forecast system on-the-spot during the plane fatigue test based on neural network. Firstly, a certain plane fatigue test AE monitorying system and trial scenario has been analyzed. Secondly, characteristic parameters has been extracted and studied based on wavelet packet technology.At last, a certain plane horizontal tails half axis monitoring in the whole plane fatigue test has been tkaen for an example to study AE monitoring system based on SOM-RBF neural network. In a word, the good results are gained.
