Abstract

This paper presents the design, development and testing of a low-cost Structural Health Monitoring (SHM) system based on MEMS (Micro Electro-Mechanical Systems) triaxial accelerometers. A new control system composed by a myRIO platform, managed by specific LabVIEW software, has been developed. The LabVIEW software also computes the frequency response functions for the subsequent modal analysis. The proposed SHM system was validated by comparing the data measured by this set-up with a conventional SHM system based on piezoelectric accelerometers. After carrying out some validation tests, a high correlation can be appreciated in the behavior of both systems, being possible to conclude that the proposed system is sufficiently accurate and sensitive for operative purposes, apart from being significantly more affordable than the traditional one.

摘要

本文提出了一种基于微机电系统（MEMS）三轴加速度计的低成本结构健康监测（SHM）系统的设计、开发和测试。开发了一个由 myRIO 平台组成的新型控制系统，由特定的 LabVIEW 软件进行管理。LabVIEW 软件还计算了后续模态分析的频率响应函数。通过将该装置测量的数据与基于压电加速度计的传统 SHM 系统进行比较，验证了所提出的 SHM 系统。在进行了一些验证测试后，可以看出两种系统的行为具有高度相关性，可以得出结论，除了价格明显更具优势外，所提出的系统对于实际应用来说足够准确和敏感。
