| Abstract: |
This paper investigates the differences between the maximum vertical bridge acceleration during a train crossing when calculated with moving loads and with vehicle-bridge interaction considering a 2D multi-body model. This influence of the interaction is currently defined for the bridge design by an additional damping value, included in Eurocode 1. For investigating the additional damping, multi-body model parameters of 14 real high-speed passenger trains were collected and evaluated statistically as presented in boxplots. This collection builds the basis for the presented results as well as a planned parameter study. The interaction effect is visualized by exemplary resonance plots, showing the overestimation of the additional damping in the current approach for some trains and even a negative additional damping value in case of the ICE 4. Also, it was discovered that there is no correlation of the dynamic bridge response to whether it is a conventional or articulated train. |
