摘要
干涉式光纤应变传感器为构件的实时频率检测提供了抗电磁干扰的新型最佳技术手段．本文分析了其在新型的电流变材料构件应用时的若干现象．提出一个位相漂移模型并用以成功处理了有关问题．由此设计的嵌埋型干涉式光纤应变传感器首次使用于受到随机外部激励的电流变结构的振动控制过程．
Interferometric fiber optic sensor is immune from electromagnetic influence and provides an optimal technical tool for vibration frequency monitoring. Some problems associated with the vibration sensing for electrorheological structures were analyzed. A phase drift model was developed and used to explain the experimental phenomena at the test. The designed embedded fiber optic strain sensor was firstly used to control the vibration of ER structure subjected to a random external excitation.
