Contributions of longitudinal track unevenness and track stiffness variation to railway induced vibration [PDF]
Journal of Sound and Vibration, 2018 Dynamic train-track interaction originates from excitation mechanisms such as longitudinal track unevenness, parametric excitation due to track stiffness variation and impact excitation due to wheel flats, wheel out-of-roundness and rail joints. Track stiffness variation can be regarded as longitudinal track unevenness in loaded condition, but for the ...

Influence of Pier Stiffness on Track-Bridge Interaction [PDF]
The International Conference on Civil Infrastructure and Construction, 2023 The bridge is a common engineering structure over which a rail track is often laid. With the introduction of continuous welded rail (CWR), major rail tracks have shifted worldwide from jointed rail to continuous welded rail. CWR eliminates fish plates and overcomes many of the drawbacks of the jointed rail, resulting in a long, smooth track with no ...

Methods for track stiffness measurement - State of the art [PDF]
, 2017 Track stiffness is a parameter which significantly influences to the track geometry deterioration, rail fatigue and deterioration of other superstructure and substructure components during the track service life. Track stiffness measurement has great theoretical and practical importance for the design of new railway lines, as well as for upgrade and ...

Qualitative Prediction Model for Dynamic Behavior of Ballasted Tracks
Applied Sciences, 2020 Theoretical, experimental, analytical, and statistical evaluations were performed to predict and assess the dynamic behavior of a ballasted track, such as the track support stiffness, track impact factor, or dynamic wheel–rail forces.

Numerical Investigation of HMA Effect on Dynamic Behavoiur of Railway Track Transition Zone [PDF]
Journal of Structural and Construction Engineering, 2018 There are many structures along the railway tracks such bridges and culverts. The track vertical stiffness suddenly changes where the track passes over these structures. Therefore, these locations are called transition zones.
