Due to the particularity of the construction technology of the CRTS I slab track bagging method, there is a certain roughness between the track slab and the mortar layer in the actual project. In this work, the W–M fractal function was used to simu

The load generated during train operation is transmitted to sleepers through rails, and then from sleepers to trackbeds. As one of the important components of the track structure, sleepers are very important to the service-life and safety of railways

In this work, a model for characterizing the ballasted track-vehicle interaction is presented. The vehicle is modelled as a multi-rigid-body system consisting of a car body, two bogie frames and four wheelsets, and the track is modelled by finite ele

In this paper, a theoretical framework for modeling the railway wagon-ballast track interactions is presented, in which the dynamic equations of motion of wagon-track systems are constructed by effectively coupling the linear and nonlinear dynamic ch

As the integrated reflection of track substructure deformations and the most important excitation for vehicle–track interactions, track irregularities show random nature, and generally being regarded as weak stationary random processes. To better e

There is no universal method to perform dynamic analysis on solid rubber anti-vibration systems. In this article, an equivalent damping ratio is introduced to account for rubber hysteresis using a resilience experiment. A new concept, NFR (Natural Fr

In light of two wheel–rail contact relations, i.e., displacement compatibility and force equilibrium, a newly developed three-dimensional (3D) model for vehicle–track interactions is presented in this paper. This model is founded on the basis of
