角钢结构光纤光栅位移传感器的研究

本文提出将两个纤维增强复合材料(FRP)封装的光纤光栅(FBG)安装于角钢梁的两个面上，用来实现对角钢梁位移大小和方向的测量，实现对角钢结构的健康检测。本文将传感器分别安装在角钢梁不同面上的各个位置，通过有限元分析模拟了角钢梁结构的位移和传感器应变传递的关系，对传感器的安装位置进行优化设计，并进行了实验验证。仿真模拟和实验结果表明，传感器安装在合理位置能够实现角钢梁一端位移的大小测量和方向判别。研究结果对于利用光纤传感器实现对角钢构成的结构如桥梁、电塔、吊车等的健康监测提供了基础研究。

Abstract

In this paper, two fiber reinforced polymer/plastic (FRP) encapsulated fiber Bragg grating (FBG) sensors were installed on the two sides of the angle steel beam, which was used to measure the displacement and direction of the diagonal steel beam, so as to realize the health inspection of the angle steel structure. The sensors were respectively installed on the different positions of angle steel beam, and the relationship between displacement and strain transmission of angle steel beam was simulated by the finite element analysis. The optimum design of sensors installation were discussed and the experimental verification was carried out. The simulation and experimental rex sults show that the sensor has the capacity to discriminate the direction and measure the size of one side of the angle steel beam displacement when installed in a reasonable position. To realize the health monitoring by using optical fiber sensors on the structures composed by angle steel, such as bridges, electric towers and cranes, and so on, a basic research was provided.
