Abstract

This work contains the results of a research of the dynamic processes in the "bridge-train" system while passenger trains move over a bridge structure (overpass) in high-speed. The article presents the methodology of mathematic modelling, and the basic differential equations of the studied system elements motion are provided. Also there is a description of dynamic interaction of the bridge-train system numerical model based on the FEM. In general, taking into account in the design scheme of the “bridge” system not only spans, but also piers with a foundation, it is possible to more accurately determine the values of the bridge natural frequencies, which is a key factor in assessing the dynamic response of a structure when passing a high-speed train.
