摘要
光纤光栅位移传感器具有精度高、本质安全、体积小和易复用等特点,但受到敏感材料的局限,大量程光纤光栅位移传感器很难获得。针对该问题,提出并实现了一种大量程的光纤光栅位移传感器,其采用行星轮系与粘贴光纤光栅悬臂梁相结合的结构,通过变换减速比来获得各种大量程;利用有限元分析法对传感器悬臂梁材料和结构进行了优化设计,研究了不同量程时该类传感器的输出特性。结果显示,该传感器输出信号的波长漂移量与位移量有着很好的线性关系,最大量程可达2 000 mm。
Abstract
Optical fiber Bragg Grating (FBG) displacement sensor has many advantages such as high sensitivity, intrinsic safety and easy multiplexing, etc. However, it is difficult to obtain a large range FBG displacement sensor due to the limitations of sensitive materials. In this paper, in order to solve this problem, a large range FBG displacement sensor is proposed and demonstrated. The planetary gear train and cantilever beam composite structure are utilized in this sensor. The FBG is pasted on the cantilever beam. Through changing the rotating ratio of the planetary gear train, different range of the sensors are achieved. Finite element analysis method is used to optimize the material and structure of the cantilever. The output characteristics of the sensor in different range are experimentally studied. The results show that the sensor has a very good linear relationship between output wavelengths and displacements and its maxima range can reach 2 000 mm.
