摘要
文中介绍了光纤布拉格光栅(Fiber Bragg Grating,FBG)分布传感的一般理论和其在损伤识别方面的研究概况,同时利用有限元分析软件对简谐载荷作用下的简支板一维方向上的应变分布进行了谐响应理论分析,并根据分析结果确定了FBG应变传感器的分布间距。
The general theory of distributed sensing of the optical fiber Bragg grating(FBG) and its research situation in damage identification are introduced in this paper.Meanwhile,the harmonic response analysis in one-dimensional direction when the simply-supported plate loaded with harmonic load is carried out with the finite element analysis software.According to the result of the theory strain distribution analysis,the distributed spacing of the FBG strain sensor is determined.
