Abstract
The Vibration detection is one of the key technologies of structural reliability. Traditional detection methods mainly focus on the analysis under single excitation, while the actual engineering problems mostly present the resonance phenomenon of multi-source excitation. Therefore, in this paper, based on the characteristics of FBG sensor, the vibration response characteristics under multi-source excitation are studied, including theoretical simulation and experimental research under multi-source excitation. On this basis, the experimental system for damage detection is built and its results show that this method by multi-excitation detection is feasible and it is sensitive to crack damage.
