中文摘要 | 為建立多點量測監測系統,以形成分佈式監測網路, 本文利用光纖光柵感測器 ,進行結構應變之量測與監測,以了解感測器之性能。首先進行拉伸壓縮試驗並和應變計及 位移計作比較,實驗結果顯示,當結構體受到載重作用時,其應變之變化和光纖光柵感測器 波長變化之間,有良好的線性關係。另由單點與兩點之三點彎距量測結果得知,因光纖光柵 感測器乃應用感測器部份之波長變化進行量測,其應變值之量測與光纖在結構體上之佈設排 放方式無關,因而可建立多點量測系統,以形成分佈式監測網路,而且當損傷破壞發生或結 構產生較大變形時,光纖光柵感測器將可獲知其破壞位置與變形破壞狀況,因此,可以作為 安全評估之用,以建構診斷監測系統。 |
英文摘要 | For establishing a multi-point monitoring system and further setting up a quasi-distributive monitoring network, this paper is concerned with a pilot study on the application of optical fiber sensors to civil engineering structures. Experimental study on comparison of measured data between the fiber Bragg grating sensors and conventional strain gages was completed first. In the study, we found that a linear relationship existed between the measured strain and wavelength shift of the optical fiber sensor under the process of loading and unloading in the steel specimens. In addition, we found that the damaged segments of the structure could be located by using multi-point optical fiber sensors distributed. |
