Effect of Long-Wavelength Track Irregularities on Vehicle Dynamic Responses

open access: yesShock and Vibration, 2019
Long-wavelength track irregularities have obvious influence on ride comfort and running stability of high-speed trains. Meanwhile, it brings risk to the inspection of track irregularities since ordinary inspection equipment has difficulties in covering ...

On the problem of the dynamical reactions of a rolling wheelset to real track irregularities

open access: yesRailway Engineering Science, 2022
We investigate numerically the dynamical reactions of a moving wheelset model to real measured track irregularities. The background is to examine whether the dynamics are suitable as the input to the inverse problem: determine the true track geometry ...

Experimental Measurement and Simulation of Railway Track Irregularities [PDF]

open access: yesCivil Engineering Journal, 2022
The study of railway dynamics is still a productive area of research given the rapid technological evolution of this transport system regarding load and speed. Morocco is no exception to this rule, especially after the commissioning of the first high-speed line in Africa.

Track irregularities stochastic modeling [PDF]

open access: yesProbabilistic Engineering Mechanics, 2013
A better understanding of the interaction between the dynamics of high speed trains and the track geometry is needed. As during its lifecycle, the train faces a great variability of track conditions, this dynamic behavior has indeed to be characterized on track portions sets that are representative of the whole railway network.

A Novel Description Method for Track Irregularity Evolution [PDF]

open access: yesInternational Journal of Computational Intelligence Systems, 2011
Track Irregularity has a significant influence on the safety of train operation. Due to the fact that the extremely large number of factors affect track irregularity it is challenging to find a concise yet effective mathematical method to describe the evolution of track irregularity.

STATISTICAL ANALYSIS OF DYNAMICAL QUANTITIES RELATED TO RUNNING SAFETY AND RIDE COMFORT OF A RAILWAY VEHICLE [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport, 2020
This paper investigates the variation of track geometrical parameters that lead to a local increase of specific dynamical quantities of a railway vehicle, possibly beyond their acceptable values.

NUMERICAL SYNTHESIS OF THE TRACK ALIGNMENT AND APPLICATIONS. PART I: THE SYNTHESIS METHOD [PDF]

open access: yesTransport Problems, 2016
This paper features a method to synthesize the track irregularities, by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such method in the numerical simulation of the dynamic behaviour
