论文摘要
电阻层析成像（ERT）基于分布式表面传感系统或感应皮肤，为结构健康监测提供了替代感测技术，为例如损伤，应变和温度提供了分布式感应的功能。但是，目前，用于传感皮肤的计算技术仅限于平面表面。在本文中，为了克服这一限制，我们将基于ERT的表面传感推广到涵盖任意形状的三维结构的非平面表面。我们构建了一个框架，在该框架中，我们使用Riemannian几何形状的技术重新重新制定ERT的图像重建问题，并以数值方式解决所得问题。我们在一系列数值和实验研究中测试了该框架。结果表明，所提出的配方的可行性以及基于ERT的传感皮肤对非平面几何形状的适用性。
Electrical resistance tomography (ERT) -based distributed surface sensing systems, or sensing skins, offer alternative sensing techniques for structural health monitoring, providing capabilities for distributed sensing of, for example, damage, strain and temperature. Currently, however, the computational techniques utilized for sensing skins are limited to planar surfaces. In this paper, to overcome this limitation, we generalize the ERT-based surface sensing to non-planar surfaces covering arbitrarily shaped three-dimensional structures; We construct a framework in which we reformulate the image reconstruction problem of ERT using techniques of Riemannian geometry, and solve the resulting problem numerically. We test this framework in series of numerical and experimental studies. The results demonstrate that the feasibility of the proposed formulation and the applicability of ERT-based sensing skins for non-planar geometries.
