GMM-FBG Current Sensor Strain Transfer Model and Paste Layer Optimization Method
摘要
Abstract
In order to optimize the strain sensor coupling characteristics of the GMM-FBG current sensor,the output amplitude of the sensor is effectively enhanceed through the geometric parameters of GMM and FBG.Firstly,the four-layer structure strain transmission model of the GMM-FBG current sensor is established,which includes fiber layer,coating layer,bonding layer and matrix layer.The rela-tionship between the basic parameters of the banding layer and the average strain transmission rate between the fiber layer and the ma-trix layer is obtained,and the accuracy of the strain transmission model is verified through the finite element simulation.In order to in-crease the average strain transfer rate of the sensor,the length,width,upper and lower thickness,elastic modulus and Poisson's ratio of the bonding layer are optimized.The results show that the strain transfer rate of the optimized sensor is effectively improved,and the output amplitude of the current sensor increases.关键词
