Advances in Materials Science and Engineering, Volume 2022, Issue 1, 2022., 2022 A ballastless track is susceptible to damage and even failure of structural components under the long‐term effects of extremely high temperatures. In this paper, considering the influence of different constraint boundaries, a 1 : 4 scaled model of a ballastless track‐bridge structural system was produced and placed in a large‐sized environmental ...

Simulation of Delamination Evolution of Slab Ballastless Track under Vertical Impact
Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 During the running of a high‐speed train, the wheel may bounce on the rail due to the track irregularity. The wheel bounce could generate a vertical impact, leading to the initiation and expansion of delamination between layers of the track structure.

Shock and Vibration, Volume 2021, Issue 1, 2021., 2021 The prevention of environmental vibration pollution induced by train operation is one of the inevitable problems in the construction of urban rail transit. With the advantage of flexible adjustment, phononic crystals (PCs) have a broad application prospect in suppressing elastic wave propagation of rail transit.

Study on the Different Effects of Power and Trailer Wheelsets on Wheel Polygonal Wear
Shock and Vibration, Volume 2020, Issue 1, 2020., 2020 The wheels of power and trailer wheelset show different polygonal characteristics since their structures are obviously different. Therefore, the frictional self‐excited vibration models of wheelset‐track systems are established based on the viewpoint of the frictional self‐excited vibration in reducing the wheel polygonal wear.

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Pier settlement is unavoidable in the construction and operation of high‐speed railways. This paper presents a work on the influence of pier settlement on additional structural stress of longitudinal connected track (LCT). First of all, the generation mechanism of additional structural stress of LCT caused by pier settlement is described in detail.
