Real-time evaluation of the mechanical qualities of ballast beds is essential for improving
tamping effort in railway maintenance. This study aims at evaluating the mechanical …

This paper proposes a new hypothesis for the formation process of short pitch rail
corrugation. An FE wheel-track dynamic model is utilized to verify the hypothesis by …

Short pitch corrugation is a quasi-periodic rail defect that induces a high level of noise and
accelerates track degradation. This paper proposes a methodology to mitigate short pitch …

The natural environment has a great effect on the interfacial bonding performance of
ballastless track in high-speed railways, and the interfacial damage analysis models of the …

The rail pad is the elastic element between the rail and the sleeper that has the role of
absorbing the mechanical stresses from the rail and reducing the vibrations and shocks …

Wheel-rail high-frequency interaction is closely related to the formation of railway short-wave
defects. Finite element (FE) method has been widely used to simulate wheel-rail dynamic …

This article presents a comparison between layered models of a railway track. All analyses
are based on semianalytical approaches to show how powerful they can be. Results are …

Purpose Maglev train travel is an efficient, modern and unconventional mode of
transportation of passengers that has many advantages over the conventional railway …

Ballasted railway tracks can be modeled using reduced/simplified models composed of
several layers of discrete components. This paper deals with the two-layer model, which is …

In this paper, the interaction of a mass moving uniformly on an infinite beam on a three-layer
viscoelastic foundation is analyzed with the objective of determining the lowest velocity at …
