摘要
研究了粘贴式光纤布拉格光栅应变传感器对柔性梁的动态响应特性,并用压电陶瓷加速度传感器作对照。结果表明,粘贴式光纤布拉格光栅传感器具有和压电陶瓷加速度传感器一致的动态响应特性,是一种高灵敏度的用于结构健康监测的新型在线监测技术。论文从应变传感模型的角度分析了光纤光栅应变传感器的轴向应变检测特性的理论基础。
Dynamic strain of flexible beam was measured by pasted FBG strain sensor, and the results were compared with that by acceleration sensor of piezoelectric ceramic. Results showed that two sensors owned the same dynamic response characteristics, and that the pasted FBG sensor used in healthy monitor of structure was a new on-line technique with high sensitivity. The theoretical basis of only responding axial strain of the pasted FBG strain sensor was analyzed based on the strain sensor model.
