Structural Health Monitoring (SHM) is essential for assessing and preserving the integrity of engineering structures. This study explores the variations in the vibration response of a 3-Degree-of-Freedom (3-DoF) structure under different damage scenarios using Power Spectral Density (PSD) and Continuous Wavelet Transform (CWT). The dataset comprises five vibration scenarios, including ambient reference (undamaged) and half-cut beam (HCB) configurations. PSD analysis identifies the HCB 2aD configuration as exhibiting the most significant deviation from the ambient reference, while CWT highlights the dominant energy contribution of sensor S1 in the undamaged condition.

摘要

Structural Health Monitoring (SHM) is essential for assessing and preserving the integrity of engineering structures. This study explores the variations in the vibration response of a 3-Degree-of-Freedom (3-DoF) structure under different damage scenarios using Power Spectral Density (PSD) and Continuous Wavelet Transform (CWT). The dataset comprises five vibration scenarios, including ambient reference (undamaged) and half-cut beam (HCB) configurations. PSD analysis identifies the HCB 2aD configuration as exhibiting the most significant deviation from the ambient reference, while CWT highlights the dominant energy contribution of sensor S1 in the undamaged condition.
