Abstract

This paper discusses the experimental validation of a numerical prediction model for train induced vibrations. The model fully accounts for the dynamic interaction between the train, the track and the soil. The track is modelled as a longitudinally invariant system, where two beams represent the rails, while a plate with a rigid cross section represents the subgrade. The track is located at the surface of a horizontally layered elastic halfspace. The translational invariance of the problem geometry enables a solution of the equations of motion in the frequency–wavenumber domain. The model is validated by means of vibration measurements that have been performed at the occasion of the homologation tests of the new HST track on the line L2 between Brussels and K¨oln during the passage of an IC train and a Thalys HST at variable speed.

Measurements and Numerical Prediction of High Speed Train Vibrations

New York, New York

This paper discusses the experimental validation of a numerical prediction model for train induced vibrations. The model fully accounts for the dynamic interaction between the train, the track and the soil. The track is modelled as a longitudinally invariant system, where two beams represent the rails, while a plate with a rigid cross section represents the subgrade. The track is located at the surface of a horizontally layered elastic halfspace. The translational invariance of the problem geometry enables a solution of the equations of motion in the frequency–wavenumber domain. The model is validated by means of vibration measurements that have been performed at the occasion of the homologation tests of the new HST track on the line L2 between Brussels and K¨oln during the passage of an IC train and a Thalys HST at variable speed.
