Abstract EN
Analysis of signals based on spectral accumulation has great potential for enabling the condition of structures excited by natural forces to be monitored using random vibration records.
This article describes cumulative harmonic analysis (CHA) that was achieved by introducing a spectral accumulation function into Berman and Fincham's conventional cumulative analysis, thus enabling potential new areas in cumulative analysis to be explored.
CHA effectively enables system damping and modal overlap conditions to be visualized without the need for transient-vibration records.
The damping and modal overlap conditions lead to a spectral distribution around dominant spectral peaks due to structural resonance.
This distribution can be revealed and emphasized by CHA records of magnitude observed even within short intervals in stationary random vibration samples.
