Xu, Lei (author), Lu, T. (author)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...journal article 2020

Xu, L. (author), Lu, T. (author)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...journal article 2020
