Damage diagnosis using time series analysis of vibration signals
A novel time series analysis is presented to locate damage sources in a mechanical system, which is running in various operational environments. The source of damage is located by solely analyzing the acceleration time histories recorded from a structure of interest. First, a data normalization procedure is proposed. This procedure selects a reference signal that is ‘closest’ to a newly obtaine...
متن کاملAn Enhanced Statistical Damage Detection Algorithm Using Time Series Analysis
A damage diagnosis approach using time series analysis of vibration signals was recently proposed by the Los Alamos National Laboratory. In this paper, the application of this approach to the damage detection of the benchmark problem designed by the ASCE task group on health monitoring is explored. The damage detection approach is modified to consider the influence of excitation variability and...
متن کاملReal-time damage detection of bridges using adaptive time-frequency analysis and ANN
Although traditional signal-based structural health monitoring algorithms have been successfully employed for small structures, their application for large and complex bridges has been challenging due to non-stationary signal characteristics with a high level of noise. In this paper, a promising damage detection algorithm is proposed by incorporation of adaptive signal processing and Artificial...

Time Series Analyses for Locating Damage Sources in Vibration Systems
A novel time series analysis procedure is presented to localize damage sources in a mechanical system. An attempt is made to pinpoint the sources of nonlinear damage by solely analysing the vibration signatures recorded from a structure of interests. First, a linear prediction model, combining Auto-Regressive (AR) and Auto-Regressive with eXogenous inputs (ARX) techniques, is estimated using a ...
