基于混沌理论的碰摩声发射特征分析与源定位
Characteristic Analysis and Localization of Acoustic Emission Source Based on Chaos Theory
摘要
Abstract
A nonlinear dynamic analysis of the acoustic emission (AE) signals in rotor rubbing was conducted based on the chaotic signal processing technique and such new features of nonlinear dynamics as correlation dimension, largest Lyapunov index and the Kolmogorov entropy were proposed herein. Simulation results reveal the neural network model employing these new features improves the localization efficiency of the AE source and contributes to the diagnosis of rotor rub- impact faults.关键词
