基于模态理论和改进GMM的声发射源识别研究
Acoustic Emission Signal Source Recognition Based on Modal Theory and Modified GMM
摘要
Abstract
Based on the modal acoustic emission signal theory,an analysis and interception method using the acoustic log cepstrum sta-tistical parameters as the feature parameters is proposed.According to the characteristic of the multiple modal acoustic emission signal,an acoustic emission source signal recognition system is proposed based on modified Gaussian mixture model.Theoretical analysis and experimental results show that the proposed method could accurately recognize the acoustic emission signal source.Meanwhile the modi-fied method could not only be applied to the recognition of emergency acoustic emission signals,but also be applied to the continuous type of acoustic emission signals.关键词
