摘要
为了实现光纤光栅传感器对基体表面应变的准确监测,以基片式光纤布拉格光栅(FBG)传感器为研究对象,推导了基片式FBG应变传感器所测应变与基体应变之间的关系,即应变传递系数表达式。实验上,将实验室封装的铜基片式应变传感器黏贴在圆柱形试件上,测定了该传感器的应变传递系数。结果表明,理论所得的应变传递系数与实验所测的应变传递系数之间的误差很小,证明了应变传递系数推导的合理性,为基片式传感器的封装和使用提供了理论指导。
Abstract
To accurately monitor the strain of surface of host materials, taking the surface fiber Bragg grating (FBG) sensor as an example, the relationship between the strain measured by the surface FBG sensor and the actual strain of the host material is deduced. The general expression of strain transfer coefficient of the surface FBG sensor is got. In experiment, the copper slice packaged FBG sensor by is adhered to the cylindrical sample surface and its strain transfer coefficient is got. The experimental result proves that the difference between strain transfer coefficients obtained in theory and in experiment is small and the theoretical derivation of the strain transfer coefficient is rational. The research results provide the theory guidance for the FBG sensor packaging and application.
