Automated analysis approaches for Structural Health Monitoring on aerospace primary structure with ultrasonic and electromagnetic sensor arrays

该项目的目的是开发永久性安装的多模态传感器，用于监测结构热点。在这种情况下，热点是结构的局部区域，被认为是缺陷形成和生长的潜在位置。本项目将探索基于超声波和涡流阵列数据的数据融合方法。阵列将用于形成覆盖热点的局部区域的地图。一个关键的研究目标是确保这些地图达到所需的分辨率，以准确地检测损害，并确保覆盖范围尽可能广泛。另一个关键挑战是设计低成本和可靠的阵列。虽然传感器将被永久安装，但相关的电子仪器可能是分开的。使用便携式电子设备的周期性原位测量可用于连接传感器和所取的读数。这可以通过有线传感器通过电磁耦合（即近场通信）。

The aim of the project is to develop permanently installed multi-modal sensors for monitoring structural hotspots. In this context a hotspot is a localised region of the structure that is thought to be a potential location for defect formation and growth. This project will explore data fusion approaches based on ultrasonic and eddy current array data. Arrays would be used to form maps of a local region covering a hotspot. A key research aim is to ensure that these maps achieve the required resolution to accurately detect damage and that the coverage region is as extensive as possible. The other key challenge is to design arrays that are low cost and reliable. Whilst the sensors will be permanently installed, the associated electronic instrumentation could be separate. Periodic in-situ measurements using portable electronics could be employed for connecting to the sensors and readings taken. This could be via wired sensors of via electromagnetic coupling (i.e. near field communication).
