Track and ground vibrations generated by high-speed train running on ballastless railway with excitation of vertical track irregularities
TL;DR: In this article, a 2.5D finite element model combining with thin-layer elements was applied to establish a vehicle-track-foundation coupled dynamic analysis model, and a quarter-car model was used to derive the equation for wheel-rail interaction force considering track irregularity.

Jianjin Yang,Shengyang Zhu,Wanming Zhai,Georges Kouroussis,Yue Wang,Kaiyun Wang,Kai Lan,Fangzheng Xu +7 more
TL;DR: A two-step time-frequency prediction method for train-induced vibrations of a superstructure of a large-scale building close to underground networks and a base isolation measure is employed to mitigate excessive building vibration are presented.

Train-induced field vibration measurements of ground and over-track buildings.
TL;DR: It is demonstrated that the traffic-induced high-frequency noise has the potential to annoy occupants on the upper floors in over-track buildings within 40m on the platform over the throat area to avoid excessive vertical vibrations and noise.
Journal ArticleDOI
Measurement of ground and nearby building vibration and noise induced by trains in a metro depot.
TL;DR: It was found that the vertical vibrations were significantly greater than the horizontal vibrations on the ground and inside the building near the testing line, and the predicted models gave a first estimation for design and assessment of newly built metro depots.

A 2dvEv- bit distributed algorithm for the directed Euler trail problem
Wen-Huei Chen,Chuan Yi Tang +1 more
TL;DR: The algorithm can be used as a building block for solving other distributed graph problems, and can be slightly modified to run on a strongly-connected diagraph for generating the existent Euler trail or to report that no Euler trails exist.

Fundamentals of vehicle–track coupled dynamics
TL;DR: In this article, a three-dimensional vehicle-track coupled dynamics model is developed in which a typical railway passenger vehicle is modelled as a 35-degree-of-freedom multi-body system.

High-speed railway lines on soft ground: dynamic behaviour at critical train speed
Christian Madshus,Amir M. Kaynia +1 more
TL;DR: In this paper, it is shown that large dynamic amplifications appear in the dynamic response of the rail/embankment/ground system as the train speed approaches an apparently critical value.

TL;DR: In this paper, a solution strategy is presented that allows for the evaluation of the second-order statistics of the response due to dynamic excitation based on the power spectral density function of the track unevenness.
