摘要
将具有压电正交异性的的传感器 (Orthotropic Piezoelectric Composite Materials,简称 OPCM)作为结构健康诊断系统中的声发射传感器 ,通过传感器的连续分布方式和电路设计 ,增强了探测结构损伤的能力 ,并减少了测试仪器的通道数量 。
The OPCM(Orthotropic Piezoeletric Composite Materials)sensors are adopted as acoustic emission sonsers in a Structure Health Mornitoring(SHM) system in this work.The fault detecting capacity of the system is improved and the number of channels of the system is reduced by distributed arrangement of the sensors and corresponding electric circuit design.The work in this paper paves a new way to a practical SHM system,and a corresponding theoretical model is also suggested.
