基于对FBG传感器薄壁圆筒材料和结构的优化设计,制作了FBG高压传感器,在0～50MPa压力范围,进行了加压和减压高压实验,实验结果表明:FBG的压力灵敏度为0.0374nm/MPa,其中心波长与压力变化有着良好的线性关系和重复性,且迟滞性好。模拟结果与实验结果很好吻合。 Based on the optimized design of the thin-wall cylinder material and structure of the FBG sensor, a FBG high-pressure sensor was fabricated. The pressure and pressure reduction experiments were carried out in the pressure range of 0 ~ 50MPa. The experimental results showed that the FBG pressure sensitivity was 0.0374nm / The center wavelength and pressure changes have a good linear relationship and repeatability, and good hysteresis. The simulation results are in good agreement with the experimental results.
