Abstract :
The application of structural health monitoring (SHM) based on fiber Bragg grating (FBG) for airships is investigated. In order to verify the validity of the FBG-based SHM in the field of airships, a qualitative strain monitoring experiment for ZHIYUAN-1 airship nosecone has been carried out. A commercial FBG interrogation system (Micron Optics sm130) is used in this experiment to measure the strain. Moreover, a finite element (FE) analysis is proceeded to confirm the result of the experiment. Results indicate the effectiveness of the FBG-based SHM system for the strain monitoring in the airship field. Finally, some proposals for future researches are provided.
