Effects of track characteristics on dynamic responses of train-bridge systems
High speed trains are an indispensable part of rapid transportation systems in many countries. As the fastest means of transport on the ground, these trains are extremely sensitive to the terrain and track conditions. Geometrical irregularities and mechanical characteristics of the track, together with inconsistencies in the lane (including bridges that support the track) are considered importa...
متن کاملDynamic analysis of high speed railway bridge under articulated trains
The problem of vehicle–bridge dynamic interaction system under articulated high speed trains is studied in this paper. A dynamic interaction model of the bridge-articulated train system is established, which is composed of an articulated vehicle element model and a finite element bridge model. The vehicle model is established according to the structure and suspending properties of the articulat...

متن کاملExperimental and Numerical Modal Analysis of a Concrete High Speed Train Railway Bridge
Train induced vibrations are a major environmental concern both in Europe and China. Besides the effect of vibrations due to passenger and freight trains and subways at relatively low speed, the study of the vibrational impact of high speed trains is of high interest. In Belgium, for example, new high speed train lines connect Brussels with Paris and London, while extensions to Amsterdam and Co...
متن کاملSeismic response analysis of high-speed railway vehicle-slab ballastless track-bridge system under near- fault pulse ground motions
This paper presents a finite element method (FEM) framework for the dynamic analysis of coupled vehicle—bridge systems under nearfield /far-field ground motions. A train car with two bogies is assumed to be represented sufficiently by a discrete, rigid multi-body system with thirty-eight degrees of freedoms (DOFs). The normal Hertzian contact theory and the tangential Kalker linear theory modif...
