Abstract:

In the test of aircraft load parameters, some structures will produce large strain concentration points. In order to solve the problem of large-scale strain monitoring of aircraft structure，a temperature-sensitized, strain-reducing fiber grating large-range strain sensor is proposed. The fiber Bragg grating sensing theory is analyzed, and a new sensor base structure is designed and analyzed by finite element method. The temperature-calibration, temperature repeatability, and strain calibration tests were performed on the packaged sensor. The results show that in the environment of 10~60 °C, the packaged fiber grating strain sensor has a temperature sensitivity of 44.959 pm/°C, which is 4.5 times stronger than bare fiber and has a linearity of 0.999. The central wavelength change at the same temperature is ±4 pm. Under the condition of 0~2000 με, the strain sensitivity is 0.79 pm/με, which is 1.52 times lower than that of bare fiber, the linearity is 0.999, and the repeatability of multiple strain cycles is ±5 pm. The packaged sensor has good sensitivity and consistency, meets the accurate measurement of the aircraft's large-scale strain, and has a promising future in the monitoring of aircraft strain concentration structure.
