光纤应变传感器在振动检测和安全评估中的应用

Optical Fiber Strain Sensor Application in Safety Inspection Under Dynamic Loading

介绍了一种利用光纤应变传感器进行动载作用下构件安全性检测的方法,以国内某过山车基础支撑为例,介绍了光纤应变传感器的安装和使用方法,并通过对传感器采集到的应变数据进行分析,结合其他现场检测数据,对受测构件安全性给出了评价。

The method of using fiber optic strain sensors for safety inspection of structural elements under dy- namic loading is introduced. In the study with fiber optic strain sensor in an in-situ test of the structural sup- porting system of a roller coaster, the method of installation and operation of fiber optic strain sensors is elabora- ted. In the comparison of the data collected from the fiber optic strain sensors and other test method, analysis is carried out to estimate the safety of the structural system.
