| 摘 要： | Hilbert-Huang Transform(HHT)是一种新型的信号处理方法,主要适用于非线性、非平稳信号的分析,其应用已经越来越广泛。本文将此方法应用在复合材料板的损伤检测实验中。在复合材料板损伤前和损伤后各采集一组信号,对其进行HHT分析。根据得到的Hilbert谱,读出结构中的损伤信息。实验结果显示,应用HHT技术可以较好的进行复合材料板上的结构健康监测。 |
| 关 键 词： | HHT 信号处理 结构健康监测 |

| Abstract: | In 1998,a new data analysis method,Hilbert Huang Transform (HHT),was developed by Norden E. Huang of NASA. This new method is proved to be ideal for non-linear and non-stationary data analysis. And it has been put into practice in several fields with good results. The method is based on two major parts: Empirical Mode Decomposition (EMD) and Hilbert Transform. This paper illustrates the feasibility of HHT as a signal processing tool for monitoring the damage on a crack plate. |
