Influence of the finite element type of the sleeper on vehicle-track interaction: a numerical study

In the framework of vehicle-track interaction, this work puts an emphasis on clarifying the influence of sleeper finite element types on system dynamic responses. Three sleeper element types, namely the rigid-body, extensible Euler-Bernoulli beam and solid element are used respectively in the track system modelling with detail mathematical...

Influence of track flexibility and spatial coherence of track irregularity on vehicle-slab track interaction: frequency-domain analysis

A straightforward and practical method of frequency-domain analysis is developed for coupled vehicle-track system. The influence of the track flexibility and spatial coherence of irregularities on frequency response of vehicle-track systems are systematically studied<br/>accounting for train velocity and irregularity wavelength. Calculations...
