摘要

本文探讨了在航空航天、海洋和其他工程应用中常见的板状结构中检测和定位损伤的关键问题。为应对这一挑战,本研究引入了边带峰值计数(SPC)技术,作为板状结构损伤检测诊断成像的基础。所提出的损伤检测算法只需要数量有限的传感器响应,从而简化了检测过程。它不依赖参考基线,从而提高了效率和准确性。这种方法能够快速、精确地识别板结构中的损伤及其位置。为了验证所提方法的有效性和适用性,我们使用了有限元模拟结果。这些结果表明,所提出的技术具有准确检测和定位损伤的能力,为在各种工程领域中加强板状结构的结构健康监测提供了一个前景广阔的解决方案。

Damage detection and localization in plate-like structures using sideband peak count (SPC) technique
This paper addresses the critical issue of detecting and localizing damage in plate-like structures, which are commonly encountered in aerospace, marine and other engineering applications. To address this challenge, the current study introduces the sideband peak count (SPC) technique as the foundation for diagnostic imaging for damage detection in plate structures. The proposed damage detection algorithm requires only a limited number of sensor responses, streamlining the detection process. It does not rely on a reference baseline, thereby enhancing its efficiency and accuracy. This approach enables rapid and precise identification of damage and its location within the plate structure. To validate the effectiveness and applicability of the proposed method, finite element simulation results are utilized. These results demonstrate the capability of the proposed technique to accurately detect and localize damage, providing a promising solution for enhancing the structural health monitoring of plate-like structures in various engineering domains.
