An efficient method for train–track–substructure dynamic interaction analysis by implicit-explicit integration and multi-time-step solution

Autor: Lei Xu, Wanming Zhai, Shengyang Zhu, Weizheng Liu

Publikováno v: Railway Engineering Science, Vol 31, Iss 1, Pp 20-36 (2022)

Abstract In this work, a method is put forward to obtain the dynamic solution efficiently and accurately for a large-scale train–track–substructure (TTS) system. It is called implicit-explicit integration and multi-time-step solution method (abbr

Mechanical characteristic variation of ballastless track in high-speed railway: effect of train–track interaction and environment loads

Autor: Shengyang Zhu, Jun Luo, Mingze Wang, Chengbiao Cai

Publikováno v: Railway Engineering Science, Vol 28, Iss 4, Pp 408-423 (2020)

Abstract Due to the fact that ballastless tracks in high-speed railways are not only subjected to repeated train–track dynamic interaction loads, but also suffer from complex environmental loads, the fundamental understanding of mechanical performa

Stochastic Analysis on the Resonance of Railway Trains Moving over a Series of Simply Supported Bridges

Autor: Tao Zhang, Taimu Jin, Jun Luo, Shengyang Zhu, Kaiyun Wang

Publikováno v: Shock and Vibration, Vol 2021 (2021)

Resonance problems encountered in vehicle-bridge interaction (VBI) have attracted widespread concern over the past decades. Due to system random characteristics, the prediction of resonant speeds and responses will become more complicated. To this en
