不同粘接材料对FBG应变传感器性能影响
|
摘要
光纤布拉格光栅应变传感器的封装结构中,光纤光栅的粘接材料直接影响其传感性能。为此,建立传感器的力学模型对光纤布拉格光栅传感器进行应变传递特性分析,通过数字仿真研究了粘接材料弹性模量对应变传递效率及应变传递稳定性的影响。基于拉力机对有机胶、无机胶、金属三类典型粘接材料封装的传感器进行了实际实验测试,验证了理论分析的合理性。理论与实验结果表明,采用金属粘接材料封装的光栅传感器力学性能最优,且其一致性、迟滞性等综合指标大约比常规有机胶高一个数量级。
In the package structure of the fiber Bragg grating( FBG) strain sensor,the bonding material of the fiber grating directly affects its sensing performance. To this end,the mechanical model of the sensor is established to analyze the strain transfer characteristics of the fiber Bragg grating sensor. The effects of elastic modulus of bonded materials on the transfer efficiency and strain transfer stability were studied by digital simulation. Based on the tensile machine,the actual experiment test was carried out on the sensors of the typical adhesive materials of organic rubber,inorganic rubber and metal,The rationality of theoretical analysis is verified. Theoretical and experimental results show that the grating sensor with metal packaging material has the best mechanical properties,and its comprehensive index of consistency and hysteresis is about an order of magnitude higher than that of conventional organic rubber.
