Development and Validation of New Methodology for Automated Operational Modal Analysis Using Modal Domain Range

Structural Control and Health Monitoring
The ability to conduct automated operational modal analysis is essential for enabling real‐time structural health monitoring without human intervention. Such automation remains a significant challenge due to the complexity of processing large datasets and the necessity of setting multiple user‐defined thresholds.

Dynamic Response Characterization of Floating Structures Based on Numerical Simulations

Energies, 2020
Output-only methods are widely used to characterize the dynamic behavior of very diverse structures. However, their application to floating structures may be limited due to their strong nonlinear behavior. Therefore, since there is very little experience

Automated operational modal analysis for the monitoring of a wind turbine blade

Proceedings of the 14th International Workshop on Structural Health Monitoring, 2023
Modal analysis has developed into a major technology for the study of structural dynamics in the past several decades. Through it, complex structural dynamics phenomena can be represented in terms of structural invariants, i.e., the modal parameters: natural frequencies, damping ratios and mode shapes.

Iterative hierarchical clustering algorithm for automated operational modal analysis

Automation in Construction, 2023
Recent developments in sensors and data processing made the structural health monitoring (SHM) sector expanding to big-data field, particularly when continuous long-term strategies are implemented. Nevertheless, main shortcomings are due to the identification and extraction of modal features.
