The application of Operational Modal Analysis (OMA) in the railway sector opens a broad field of opportunities. The validation of the numerical model employed in the design phase is usually performed employing data obtained in static tests.
The drawback is that some suspension parameters, such as dampers, only have an influence in the dynamic behaviour and not in the static behaviour. Because of that, the use of the mode shapes identified from track measurements in combination with the static tests leads to a more accurate validation of the numerical model.
