Abstract

The article presents a method for identifying and analyzing the selected dynamic characteristics of deformation of a bridge structure using fiberoptic Bragg sensors with an inclined lattice. This paper describes the basic principle of operation of sensors based on a fiber Bragg lattice. Vibration modes were also determined using time series analysis with a high sampling rate. With the help of appropriate mathematical models (filters) and spectral analysis, it was possible to identify and describe the oscillation frequencies of the structure, which were compared with the theoretical model described by the dynamic behavior of the bridge. This model has been tested on a car and pedestrian bridge. With the help of the developed mathematical and experimental model, data were processed, and vibration modes were determined during vibration of bridge structures.

使用带倾斜栅格的光纤布拉格传感器进行桥梁振动分析

文章介绍了一种利用带倾斜晶格的光纤布拉格传感器识别和分析桥梁结构变形的选定动态特性的方法。本文介绍了基于光纤布拉格晶格的传感器的基本工作原理。此外，还利用高采样率的时间序列分析确定了振动模式。在适当的数学模型（滤波器）和频谱分析的帮助下，可以确定和描述结构的振动频率，并将其与桥梁动态行为所描述的理论模型进行比较。该模型已在汽车桥和人行桥上进行了测试。在开发的数学和实验模型的帮助下，对数据进行了处理，并确定了桥梁结构振动时的振动模式。
