摘要:
振动信号是表征各种机械设备、桥梁、建筑稳定性的重要因素。在重大工程结构的测量中，振动信号频率高，加速度值也较大，信号的采集、处理相对容易。而对于频率在50 Hz以下的振动信号，例如地震监测、地质勘探等，振动信号幅值小，有效信号易被忽略，一般的光纤光栅振动传感器不能满足低频信号的测量。该文针对低频振动信号的采集问题，对悬臂梁结构的光纤布拉格光栅加速度传感器进行阐述，与嵌入式结构、芯轴式结构的加速度传感器作横向比较，整理光纤光栅加速度传感器的发展历程，并对光纤加速度传感器的发展作进一步展望。
Abstract:
Vibration signal is an important factor to represent the stability of various mechanical equipment,Bridges and buildings.In the measurement of major engineering structures,the frequency of vibration signal is high and the acceleration value is large,so the acquisition and processing of the signal is relatively easy.However,for vibration signals with frequencies below 50 Hz,such as seismic monitoring and geological exploration,the amplitude of vibration signals is small,and the effective signals are easy to be ignored.General fiber Bragg grating vibration sensors cannot meet the measurement of low-frequency signals.This article in view of the low frequency vibration signal acquisition problem of cantilever beam structure acceleration sensor of optical fiber Bragg grating is expounded,and the acceleration sensor of the embedded structure,core shaft structure,horizontal comparison of finishing the development of fiber Bragg grating acceleration sensor,and further prospect to the development of optical fiber acceleration sensor.
