基于FBGs的复合材料桨叶承载与损伤监测

open access: yesZhendong Ceshi yu Zhenduan
针对复合材料桨叶在运行过程中的结构健康监测问题,提出了一种基于光纤光栅传感器(fiber Bragg grating sensor,简称FBGs)的桨叶实时监测方法。首先,采用内埋FBGs的方式对复合材料桨叶运转过程中的结构动态响应进行实时监测,分别采集不同叶偏角、转速以及测点位置的动态应变;然后,借助三维数字图像相关技术(digital image correlation,简称DIC‑3D)对桨叶表面位移场进行同步监测;最后,在复合材料叶片内引入冲击损伤,对比完整结构和含损伤结构的FBGs监测信号 ...
