摘要
运用智能材料和智能结构的基本思想，采用压电片阵列对结构的损伤进行监测，通过传感器所得到的结构的动态应变信息来反映结构的损伤程度和损伤位置。从实验结果来看，监测效果比较理想，为今后进一步研究太空柔性结构的健康监测奠定了良好的基础。
According to the basic idea of smart material and smart structure we detect the damage of the struc- ture using piezoelectric patch array in this paper. The information about the location and degree of the damage can be acquired through the structural dynamic strain. The monitoring result is good in our experiment. This builds the better foundation for the deep research of the health monitoring about the space flexible structure.
