摘要

杨氏模量作为材料力学中的一个重要参数，在工程设计和教学研究中起着重要的作用。光纤布拉格光栅作为目前最流行的光学传感器器件，具有灵敏度高、抗干扰能力强等突出优点。因此，本文选用42CrMo合金钢作为测量材料。提出了一种利用光纤布拉格光栅和压力传感器测量金属材料杨氏模量的设计方法。通过实验得到了待测金属的杨氏模量。并与标准材料的杨氏模量进行了比较。设计方法简单，测量精度高。

Measurement of Young's Modulus of Metallic Materials Based on Fiber Bragg Grating

Young's modulus, as an important parameter in material mechanics, plays an important role in engineering design and teaching research. Fiber Bragg grating, as the most popular optical sensor device, has outstanding advantages such as high sensitivity and strong anti-interference. Therefore, this article uses 42CrMo alloy steel as the measurement material. A design method for measuring the Young's modulus of metallic materials using fiber Bragg gratings and pressure sensors is proposed. The Young's modulus of the metal to be tested is obtained through experiments. And compared with the Young's modulus of standard materials. The design method is simple and the measurement accuracy is high.
