摘要
光纤光栅传感器技术应用于力学测试是国内外正在发展的一门新技术。本文基于光纤光栅传感的基本原理，介绍了一种用于位移测量的应变传感器，测得应变与位移变化具有良好的线性特点，重复性好；对该传感器的测量过程进行了有限元模拟，并与实验值进行了比较。
The application of fiber optic Bragg sensor to mechanical measurement is a new technology in recent years. Based on the principle of FBG, a displacement-strain sensor is introduced in this paper. The experiments of this sensor display its good Iinearity between the displacement and strain, and this linearity has the feature of repeatability. The simulated result with thin shell element is compared to the experiments, which identified the design concept of this sensor.
