摘要

为准确识别结构位移动态变化的幅值与方向，本文提出一种基于凸台-凹槽结构增强等强度梁应变响应的高灵敏度光纤光栅位移传感器，并系统完成了测量原理、结构设计、温度补偿及样机性能验证。实验结果表明，该传感器具备双向位移感知能力，在±60 mm量程内，传感器灵敏度为63.446 pm/mm，综合测量精度为0.145 9 mm，且在稳定性、重复性、迟滞、温度适应性及抗蠕变性能方面表现良好。现场应用结果表明，3个传感器在某市地铁隧道支护管片变形监测中运行稳定，可有效获取结构变形信息，适用于土木与机械工程领域的双向位移精确监测。

Abstract

To accurately capture the amplitude and direction of dynamic structural displacement variations， a high-sensitivity fiber Bragg grating （FBG） displacement sensor based on a boss–groove structure is proposed to enhance the strain response of a uniform-strength beam. The sensor provides bidirectional displacement sensing capability. Its measurement principle， structural design， temperature compensation method， and prototype performance evaluation were systematically investigated. Experimental results show that， over a measurement range of ±60 mm， the sensor achieves a sensitivity of 63.446 pm/mm and a comprehensive measurement accuracy of 0.145 9 mm， while exhibiting favorable stability， repeatability， hysteresis performance， temperature adaptability， and creep resistance. Field application results further indicate that three deployed sensors operated stably and effectively captured structural deformation information for support segments in a subway tunnel in a certain city. The proposed sensor is therefore suitable for precise bidirectional displacement monitoring in civil and mechanical engineering applications.
