中文摘要：
利用光纤光栅（FBG）传感器对基体表面应变进行测量,通常利用胶粘剂将光纤光栅传感器粘贴在基体表面,使其与基体协调变形。但胶粘剂在不同表面的粘接性能不同,对应变测量所造成的影响也就存在差异。针对这一问题,本文通过实验,简化应变传递模型,对比FBG传感器粘贴在等强度梁以及标准树脂试件的应变测量结果。结果表明：胶粘剂在基体表面的剪切强度越大,表面粘贴式FBG传感器的应变传递系数也越大。
英文摘要：
Fiber bragg grating（FBG）sensor is usually pasted on the substrate to measure the surface strain,so it can achieve the compatibility of deformation.But different adhesive show various property on different substrate,thus influence the strain measurement result.In response to this problem,an experiment was conducted to simply the strain transfer model.The strain result measured by FBG sensor pasted on the beam of uniform strength and the standard resin specimen was compared.The results show that the greater the shear strength of the adhesive on the substrate,the strain transfer coefficient of surface-bonded FBG sensor is better.
