Error Analysis of FBG Sensors Bonded on LowModulus Host Materials
摘要
Abstract
FBG sensor has been widely used in measuring the strain of host material. The existing of FBG sensor af⁃fects strain distribution of the host material,and the host material does not contact the optical fiber. However,may result in a decrease of strain measurement accuracy. So,the strain relationship between the optical fiber and host material was needed to study to improve the measurement accuracy.A theoretical model of strain transfer was devel⁃oped to include the influence of FBG sensor. Subsequently,the theoretical predictions were validated by finite ele⁃ment analysis. The effect of parameters on strain transfer rate was discussed according to the current theoretical analysis. the error between theoretical solution and FEA was controlled within 3%. The theoretical model satisfied accuracy requirement of the FBG sensors,which is considered as a guidance for its practical application.关键词
