摘要

结构缺陷定位的常用方法基于参考系统和缺陷系统之间不同传感路径上测量的速度差(VD)或振幅比(AR)(或散射衰减)。传感路径上的高值表明该路径上存在缺陷的概率较高。我们介绍了一种基于新开发的拓扑声学(TA)传感技术的替代方法,利用 Lamb 波定位板状结构中的缺陷。拓扑声学传感利用声波几何相位的变化来检测支撑介质中的扰动。这种方法使用几何相位变化指数(GPC-I)作为检测指标,而不是 VD 或 AR。基于 Abaqus/CAE 软件有限元法 (FEM) 的计算验证了所提出的基于 GPC-I 的缺陷定位方法的有效性。与基于 VD 或 AR 的方法相比,GPC-I 方法能以更高的灵敏度和准确度定位板表面的随机位置缺陷。

Defect localization in plate structures using the geometric phase of Lamb waves
Commonly used methods for defect localization in structures are based on velocity differences (VD) or amplitude ratio (AR) (or attenuation due to scattering) measured along different sensing paths between a reference system and a defective system. A high value on a sensing path indicates a higher probability of the presence of defect on that path. We introduce an alternative approach based on the newly developed topological acoustic (TA) sensing technique for localizing defects in plate structures using Lamb waves. TA sensing exploits changes in geometric phase of acoustic waves to detect perturbations in the supporting medium. This approach uses a geometric phase change – index (GPC-I), a measure of the geometry of the acoustic field averaged over a spectral domain, as detection metric in lieu of VD or AR. Calculations based on the finite element method (FEM) in Abaqus/CAE software verifies the effectiveness of the proposed GPC-I-based defect localization method. Randomly located defects on the surface of a plate are localized with higher sensitivity and accuracy, by the GPC-I method in comparison to VD or AR-based methods.
