Zhendong Ceshi yu Zhenduan为了提高分布式光纤传感器监测结构动态响应的精度并提高损伤诊断的准确性，运用长短期记忆神经网络，建立布里渊增益谱‑频率数据关系模型，确定布里渊光时域分析技术中振幅传输模式扫描的固定频率。基于分布式光纤振动传感信息沿光纤密集分布特点，通过计算应变传递率梯度，提出了基于分布式动应变传递率梯度的损伤指标。不同损伤程度的悬臂梁分布式光纤振动传感实验表明，该方法能够实现结构损伤位置的诊断，且对毫米级裂纹仍有较强的敏感性。

Gaoya dianqi, 2018 为将分布式光纤传感技术应用于变压器绕组变形监测,文中对基于不同敷设方式的光纤监测变压器绕组变形进行了研究,设计并制作了内径侧、外径侧和表面敷设分布式光纤的变压器绕组模型,并对电磁线结构和绕组绕制工艺进行了相应的改进。最后,对上述3种绕组模型进行了局部变形试验,并利用基于布里渊散射原理的分布式光纤应力监测系统对其应变分布进行了监测和评估。结果表明,敷设于绕组外径侧的分布式光纤预应变较大,测量结果的重复性也较差;敷设于绕组内径侧和表面的分布式光纤预应变较小,应变分布较均匀,且测量结果重复性较好;但是 ...
