On effects of track random irregularities on random vibrations of vehicle–track interactions
Probabilistic Engineering Mechanics, 2017Abstract 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 expose the full statistical characteristics of track random irregularities on amplitude and ...

Influences of Infrastructure Property on the Train-Track Interaction Due to Track Irregularities
2020The paper presents a study of the dynamic behavior of a high-speed train-track-bridge system during the train crossing multi-span concrete box girder bridges due to track irregularities. A coupled finite element–multibody dynamics (FE-MBS) model including the train sub-model, the ballastless track sub-model, the wheel-rail contact sub-model and the ...

Random Field Modeling of Railway Track Irregularities
Journal of Transportation Engineering, 1995Track irregularity is considerably important in track-vehicle studies. Recorded data of these irregularities form a basis to develop track standards. This also helps specify track inputs to the vehicles. In this paper random field models for vertical irregularity data obtained from Indian railways has been presented.

An Inverse Analysis Method for the Assessment of Track Irregularity
2012This paper presents an experimental study of a new assessment of track irregularity based on a new inverse analysis method. Two tri-axial accelerometers are mounted on the axel box of a track recording vehicle to measure the dynamic response. And according to the acceleration responses at axel box, the spatial path of the moving wheel on the track will
