Abstract
A numerical approach for a simulation of the effect of moving loads on the vibration of a railway track and the vibration of a structure in the surrounding of the track is presented. Comparativea nalysesa rep erformed. The rails, sleepers, elastic pads as well as the structure in the surrounding are described by finite elements, and the ballast and subsoil by boundary elements. The simulation is performed in the frequency domain. The investigation indicates that the speed of a moving load has a significant in fluence on the track and ground vibrations. The results show that in order to obtaina more realistic characteristic of the structural response to the ground motions it is not enough just to consider the vertical component of the ground motions.
