摘要: In this article, strain transfer characteristics of fiber Bragg grating (FBG) sensors is analyzed with finite element method axial distribution each layer described, and influencing factors the obtained, including bonded length sensor, thickness as well Young’s modulus adhesive. The calculation results are verified by tensile tests metal specimens. reveal that at suitable bonding conditions, FBG have good sensing characteristics. addition, it also easy for chirping phenomenon to occur if not sufficient. efficiency can be improved reduced either increasing or decreasing adhesive, choosing proper
