Dynamic calibration for Bragg grating strain measurement system Open
摘要: 为了能够简单精确地标定出Bragg光栅应变测试系统的应变拉伸系数，通过分析测试系统的解调原理，提出了运用陶瓷制动器的逆压电效应标定该系统的方法。对系统的8路应变测试通道进行了标定实验，将每路通道的实验数据进行线性拟合，分别得到了Bragg光栅应变拉伸量与解调信号相位差的关系曲线，从而确定了每路通道的应变拉伸系数，分析表明系数的标定相对误差在0.002 m/（）以内，标定结果具有较高的精度。 关键词: Bragg光栅 / 应变测试 / 动态标定 / 陶瓷制动器
