目的 验证粘贴式FBG传感器对宽温度环境的适应性。方法 通过高低温循环试验研究温度对传感性能的影响。对FBG传感器安装参数进行分析和优化设计,用353ND、UHU PLUS、ergo 5800和502等4种胶黏剂在铝合金表面粘贴安装FBG传感器,制成FBG测试样件。对测试样件进行高低温循环测试,测试试验前后FBG的传感性能,分析高低温循环对FBG传感性能的影响情况。结果 高低温循环后,FBG传感器中心波长产生了0.015~0.642 nm偏移,传感器灵敏度下降范围为0.563%~2.07%。结论 在实际选择FBG传感器胶黏剂时,需特别关注胶黏剂的温度适用范围参数,以减少胶黏剂温度适应性对测试结果的影响,提高测量精度。 |

The work aims to verify the adaptability of the adhesive FBG sensor to the environment. The effect of high and low temperature cyclic test on the performance of the sensor was studied. In order to analyze and optimize the installation parameters of FBG sensor, four kinds of adhesives such as 353ND, UHU PLUS, ergo 5800, and 502 were used to fix the FBG sensor on the surface of aluminum alloy to obtain the FBG specimen. Then, the specimen was subject to high and low temperature cyclic test and the sensing performance of FBG specimen was analyzed before and after the test. The effect of high and low temperature cycle on the performance of FBG sensor was explored. After high and low temperature cycle, the central wavelength of the FBG sensor changed from 0.015 nm to 0.642 nm and the sensitivity drop range of the sensor was 0.563%~2.07%. In practical engineering applications, special attention should be paid to the applicable range of adhesive temperature, so as to reduce the effect of temperature adaptability of adhesive on the test results and improve the measurement accuracy. |
