Semi-Automated Operational Modal Analysis Methodology to Optimize Modal Parameter Estimation
Journal of Optimization Theory and Applications, 2020Nowadays, long-term monitoring systems rely on the efficient implementation of automated methodologies to extract the modal parameters of buildings and bridges to assess their structural integrity. However, modal parameter estimation, usually, requires a certain level of user interaction, mainly when parametric system identification methods are used ...

Fully automated (operational) modal analysis
Mechanical Systems and Signal Processing, 2012Abstract Modal parameter estimation requires a lot of user interaction, especially when parametric system identification methods are used and the modes are selected in a stabilization diagram. In this paper, a fully automated, generally applicable three-stage clustering approach is developed for interpreting such a diagram.

Automated Operational Modal Analysis Based on DBSCAN Clustering
2020 International Conference on Intelligent Transportation, Big Data & Smart City (ICITBS), 2020Stochastic subspace identification uses the frequency stability graph as the judgment standard of recognition results, and the introduction of clustering algorithm makes the automatic recognition of stability graph possible. At present, the clustering algorithm generally has subjective input parameter selection, complex algorithm theory and human ...

Infinite mixture models for operational modal analysis: An automated and principled approach
Journal of Sound and Vibration, 2021Abstract The development of a fully automated system identifier without the need for human intervention, is a key step for real-time vibration-based Structural Health Monitoring (SHM). In this paper a novel approach based on the Dirichlet Process Gaussian Mixture Model (DP-GMM) is developed in order to analyze the stabilization diagram. The aim is to

Automated eigensystem realisation algorithm for operational modal analysis
Journal of Sound and Vibration, 2014Abstract The eigensystem realisation algorithm (ERA) is one of the most popular methods in civil engineering applications for estimating modal parameters. Three issues have been addressed in the paper: spurious mode elimination, estimating the energy relationship between different modes, and automatic analysis of the stabilisation diagram.

Automated Operational Modal Analysis on a Full-Scale Wind Turbine Tower
2023This chapter is concerned with the automated extraction of modal parameters (frequency and damping estimates) from accelerometer data measured on a full-scale wind turbine tower without its nacelle and blades installed. The proposed algorithm is based on an existing Operational Modal Analysis research software employing the Stochastic Subspace ...

Automated Operational Modal Analysis of a Helicopter Blade with a Density-Based Cluster Algorithm
AIAA Journal, 2023Automated operational modal analysis (AOMA) is a common standard for unsupervised, data-driven, and output-only system identification, utilizing ambient vibrations as an environmental input source. However, conventional AOMA approaches apply the [Formula: see text]-means clustering algorithm (with [Formula: see text]) to discern possibly physical and ...
