Journal ArticleDOI
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.
Journal ArticleDOI
High-speed train-track-bridge dynamic interactions - Part I: theoretical model and numerical simulation
Wanming Zhai,H. Xia,Chengbiao Cai,Mangmang Gao,Xiaozhen Li,Xiangrong Guo,Nan Zhang,Kaiyun Wang +7 more
TL;DR: In this paper, the authors present a framework to systematically investigate the high-speed train-track-bridge dynamic interactions, aiming to provide a method for analysing and assessing the running safety and the ride comfort of trains passing through bridges.
Journal ArticleDOI
Interface damage and its effect on vibrations of slab track under temperature and vehicle dynamic loads
TL;DR: In this article, a three-dimensional finite element model was proposed to investigate the interface damage occurred between prefabricated slab and CA (cement asphalt) mortar layer in the China Railway Track System (CRTS-II) slab track system.
Journal ArticleDOI
High-speed train–track–bridge dynamic interactions – Part II: experimental validation and engineering application
TL;DR: In this article, the authors presented an onsite experiment of the train-track-bridge interaction dynamics carried out on the Beijing-Tianjin high-speed railway, and then the experimental results are used to validate the train -track-bridges interaction simulation software (TTBSIM).
Journal ArticleDOI
Coupling Model of Vertical and Lateral Vehicle/Track Interactions
TL;DR: In this article, a new dynamic model of vehicle/track interaction is presented, which considers the vehicle and the track as a whole system and couples the vertical interaction with the lateral interaction.
