Abstract EN
With the continuous development of mechanical automation, the structural health monitoring techniques are increasingly high requirements for damage detection.
So structural health monitoring (SHM) has been playing a significant role in terms of damage prognostics.
The main contribution pursued in this investigation is to establish a detection system based on ultrasonic excitation and fiber Bragg grating sensing, which combines the advantages of the ultrasonic detection and fiber Bragg grating (FBG).
Differencing from most common approaches, a new way of damage detection is based on fiber Bragg grating (FBG), which can easily realize distributed detection.
The basic characteristics of fiber Bragg grating sensing system are analyzed, and the positioning algorithm of structural damage is derived in theory.
On these bases, the detection system was used to analyze damage localization in the aluminum alloy plate of a hole with diameters of 6 mm.
Experiments have been carried out to demonstrate that the sensing system was feasible and that the estimation method of the location algorithm was easy to implement.
