Analysis and Design of Steel Bridges with Ballastless Track

Procedia Engineering, 2015
AbstractCurrently the modernisation of railways is in progress in a large global scale. While classic ballast is verified in the long term and quite popular, the structural solutions using more quality materials (concrete, asphalt) are more and more preferred.

Intelligent recognition of defects in high‐speed railway slab track with limited dataset

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 6, Page 911-928, 15 March 2024.
Abstract During the regular service life of high‐speed railway (HSR), there might be serious defects in the concrete slabs of the infrastructure systems, which may further significantly affect public transportation safety. To address these serious issues and fulfill the regular functions of HSR, the traditional methods for railway engineers involve ...

Bio‐inspired structure constraints following control for enhancing hunting stability of high‐speed trains

IET Control Theory &Applications, Volume 18, Issue 3, Page 316-334, February 2024.
To address the issue of anomalous car‐body hunting motion, this study proposes a constraint‐following control method that leverages actuators installed in the suspension system to achieve the beneficial non‐linearity of the bio‐inspired structure.

Ballastless track in tunnels [PDF]

, 2016
Během posledních let se neustále zvyšují nároky na konvenční železniční tratě se štěrkovým kolejovým ložem. Snaha dosáhnout vyšších maximálních rychlostí a zatížení na nápravu dala vzniknout konstrukci pevné jízdní dráhy.
