- Abstract
Damping parameters of ballasted track on railway bridges – part I: vertical relative displacements in the ballast The effects of the ballasted track on the dynamic properties of railway bridges have been the focus of pertinent scientific discourse up to the present. The discrepancies between dynamic calculations and measurements have thus constituted core challenges in railway bridge engineering to this very day. A wide range of mechanical models allows for dynamic calculation of bridge vibrations. However, pertinent parameters vary considerably and thus call for targeted research of ballasted track. Such focused and isolated analysis of the dynamic behaviour on railway bridges is conducted at a special large‐scale test facility at TU Wien. This paper focuses on the energy dissipation as a result of vertical displacements in the ballasted track with special consideration of damping parameters gained from combined theoretical and empirical calculations. The core parameters thus obtained show a significant dependency on the acceleration level. They are subsequently integrated into a comprehensive, detailed model.
