摘要

本文介绍了一种与惯性传感器和信号调节技术相结合的非侵入式结构健康监测(SHM)方法。该建议使用 IMU(惯性测量单元)三轴加速度计和陀螺仪的信号,连续测量因地震振动而运动的结构的位移。该系统被称为 "惯性位移监测系统 "或 "IDMS",采用卡尔曼滤波器等方法来减小 IMU 的信号误差,以减少白噪声的影响;采用切比雪夫滤波器来隔离地震运动的频率值;采用称为零速度观测更新(ZVOB)的校正算法来检测地震振动并减少外部扰动的影响。因此,IDMS 是一种用于测量结构在地震振动引起的运动时的位移的方法,可提供及时发现故障的信息。

Inertial Methodology for the Monitoring of Structures in Motion Caused by Seismic Vibrations
This paper presents a non-invasive methodology for structural health monitoring (SHM) integrated with inertial sensors and signal conditioning techniques. The proposal uses the signal of an IMU (inertial measurement unit) tri-axial accelerometer and gyroscope to continuously measure the displacements of a structure in motion due to seismic vibrations. A system, called the “Inertial Displacement Monitoring System” or “IDMS”, is implemented to attenuate the signal error of the IMU with methodologies such as a Kalman filter to diminish the influence of white noise, a Chebyshev filter to isolate the frequency values of a seismic motion, and a correction algorithm called zero velocity observation update (ZVOB) to detect seismic vibrations and diminish the influence of external perturbances. As a result, the IDMS is a methodology developed to measure displacements when a structure is in motion due to seismic vibration and provides information to detect failures opportunely.

期刊介绍: ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
