Correlation Analysis between Rail Track Geometry and Car-Body Vibration Based on Fractal Theory
Fractal and Fractional, 2022 The effect of track geometry on vehicle vibration is a major concern in high-speed rail (HSR) operation from the perspectives of ride comfort and safety. However, how to quantitatively characterize the relation between them remains a problem to be solved

Analysis of Influencing Mechanism of Subgrade Frost Heave on Vehicle-Track Dynamic System
Applied Sciences, 2020 Uneven subgrade frost heave has been a severe problem for the operation of high-speed railways in cold regions. In order to reveal the influencing mechanism of frost heave on the vehicle-track system, a novel FEM (finite element method) model based on an

Effect of Track Irregularities on the Response of Two-Way Railway Tracks [PDF]
Applied Sciences, 2019 In predicting the response of track from a moving train only one track is generally considered. However, the effect of ground vibrations from one track and its effect on the nearby tracks has not been studied completely. Therefore, in the present paper, the effect of track irregularities and speed on the prediction of two-way tracks response is ...
