Robust structural damage identification through VMD and feature-level fusion of multi-source vibration signals

Key Points

• Damage identification improved significantly with feature-level fusion of multisource vibration signals, demonstrating effective structural monitoring.
• The method utilized variational mode decomposition (VMD) for analyzing the vibration signals collected from multiple sources, enhancing the detection accuracy.
• Observational analysis highlights the importance of integrating multiple signal sources to improve diagnostic capabilities in structural health monitoring.
• The approach suggests that robust identification can lead to better maintenance practices and increased safety for infrastructure.
