基于信息融合技术的结构损伤检测方法

In the field of structural damage detection, different damage detection methods have different sensitive level to structural damage. In order to improve the accuracy of structural damage detection, information fusion technology was used in structural damage detection here. Using the weighted average method, the simply voting method and the D-S evidence theory, information was fused at different levels, structural damage state was obtained. The feasibility and effectiveness of the proposed method were verified using honeycomb sandwich composite beams damage detection tests. The results showed that the proposed method can accurately figure out if structural damage happens and structural damage's position.
