Research on Damage Detection and Identification of Truss Bridge Components Based on Air-land Amphibious UAV
In the process of operation,the truss bridge components will have different degrees of damage.The existing detection methods are costly,complex to implement,and the damage assessment is relatively rough.In order to solve this problem,this paper combines the air-land amphibious UAV equipment and vibration signal processing technology invented in the early stage,obtains its state information by extracting the modal parameters of bridge truss,and uses signal processing methods such as Fourier transform to identify and locate the damage of bridge truss,so as to realize the intelligent identification of bridge truss damage.
