| 摘 要： | 采用小波变换作为复合材料层合板损伤检测信号的分析工具,在获得复合材料层合板的动力学响应的基础上,应用小波分析工具对结构响应信号进行提取,对含噪声信号则先作降噪声处理,然后再进行小波分解,根据各种响应信号对损伤的灵敏度,选择损伤特征,通过捕捉结构出现损伤的时刻,实现复合材料损伤实时监控.

| Abstract: | The wavelet analysis is adopted in this article for dealing with the signal. The main subject is calculating the dynamics response of samdwich board. Then decompose the structure response signal with wavelet tools after deducing the annoyance. The real-time monitoring for composite material is carried out by catching the damaging moment. Then choose the damage character by comparing the susceptibility to damage among every response signals. |

| Keywords: | laminates wavelet real time monitoring damage detection |
