Özet

This paper investigates the dynamic behavior of a quarter car vehicle system using the Operational Modal Analysis (OMA). This method is applied using one of the major techniques of the Blind Source Separation (BSS) which is the Independent Component Analysis (ICA). Compared to the classical modal analysis, the Operational Modal Analysis presents the advantage that it is only based on the vibratory responses of the structure in order to identify its modal parameters. To validate this approach in the case of a quarter car vehicle model, the estimated results obtained by the OMA methods are presented and compared with those obtained by the modal recombination method.
