| 摘 要： | 通过对应变波的传播过程分析，研究了FBG（Fiber Bragg Grating）应变传感器的动态特性，给出了应变波传递到裸FBG上的滞后时间，估算了FBG应变传感器的最高工作频率，并将自行封装的FBG应变传感器粘贴于海底管线模型上进行了振动台试验，结果表明，FBG应变传感器适用于低频振动系统的监测需要，在对低频振动系统的监测中具有良好的工作性能。

| Abstract: | this paper investigates dynamic characteristics of a Fiber Bragg Grating(FBG) strain sensor by analyzing transmit course of strain waves,and gives the lag time for strain waves to transfer to bare FBG.The highest working frequency of FBG is also estimated.The result shows that the FBG strain sensor is applicable to the measurement of low frequency vibration in engineering.In the end,FBG strain sensors are sticked on an offshore pipeline model for a shake table test and the result shows their good capability in monitoring dynamic characteristics of vibration systems with low frequency. |
