| 摘 要： | 蜂窝夹层复合材料结构是复合材料在飞机上所采用的一种重要形式。文中采用基于压电元件的应力波技术对蜂窝夹层结构的脱粘损伤进行了监测研究，研究采用梁及板两种典型结构试件，并采用小波分析对应力波检测信号进行了数据处理，提取了两种可有效表征脱粘损伤的应力波因子，初步实现了一套蜂窝夹层结构损伤的实时在线监测系统。

| Abstract: | Sandwich composite material is a very important structure on airplane.This paper introduces the research of monitoring the delamination damage in the sandwich structure by adopting the stress wave factor technology based on piezoelectric element. Two kinds of typical structures, the beam and the plate, are used in the research. Wavelet analysis is used to process the monitored stress wave signal. Two kinds of effective stress wave factor are decided through the research, and a system to monitor damage in sandwich structure is established. |
