摘要
采用不绣钢管对光纤布拉格光栅（FBG）进行封装并对其进行标定,粘贴在钢衍架表面测量结构的应变,封装光纤光栅显示了良好的传感性能,与电阻应变片测量结果吻合良好。封装后的光纤布拉格光栅传感器操作容易,便于安装,为建立工程结构健康监测系统奠定了基础。
Fiber Bragg grating(FBG) sensors with stairless steel tube jacket are characterized and attached to the surface of steel truss to measure strain. The sensors show close agreement with resistance strain gages. Operation of FBG with jacket is very convenient, which make it possible to establish a structural health monitoring system based on fiber optic sensors.
