本文报导了一种工程上可实际应用的新颖的光纤光栅压力传感器.该传感器把轮辐式结构和光纤光栅相结合,将光纤光栅粘贴于其中一片轮辐之上,室温下,在0~30 KN的压力变化范围内,光纤光栅中心反射波长的变化与压力成良好的线性关系,线性度高达0.999 8,灵敏度为0.028 43 nm/KN.研究结果表明,本传感系统具有结构简单、操作方便、精度高、滞后小、重复性好、结构高度小、重量轻等优点. In this paper, a novel fiber grating pressure sensor, which can be applied in practice, is introduced.The sensor combines a spoke structure with an optical fiber grating and affixes a fiber grating onto one of the spokes, and at 0-30 KN Within the range of pressure variation, the change of the reflection wavelength of the FBG becomes a good linear relationship with the pressure, the linearity is up to 0.999 8 and the sensitivity is 0.028 43 nm / KN.The results show that the sensing system has the advantages of simple structure, convenient operation, High, small hysteresis, good repeatability, small structure, light weight and other advantages.
