Lightweighting of railway axles for reduction of unsprung mass and track access charges [PDF]
, 2020 The potential for lightweighting of railway axles was investigated to primarily reduce the unsprung mass of rail vehicles. The reduction of unsprung mass equates to an overall lighter train, which will help to reduce track damage, energy consumption and ...

Journal of Advanced Transportation, Volume 2025, Issue 1, 2025.As an important part of modern transportation infrastructure, high‐speed rail (HSR) networks not only reduce the spatiotemporal distance between regions but also generate widespread spillover effects through mechanisms such as population mobility, technological innovation, and market expansion. Based on the city‐level panel data from 2008 to 2021, this

Experimental and Numerical Investigation into Formation of Metro Wheel Polygonalization
Shock and Vibration, Volume 2019, Issue 1, 2019., 2019 We present a detailed investigation of the mechanism of metro wheel polygonal wear using on‐site experiments and numerical simulation. More than 70% of metro wheels exhibit 6th–8th harmonic‐order polygonal wear; the excitation frequency of the polygonal wear is located in the 50–70 Hz interval at an operating speed of 65–75 km/h.

Estimation of Cement Asphalt Mortar Disengagement Degree Using Vehicle Dynamic Response
Shock and Vibration, Volume 2019, Issue 1, 2019., 2019 Cement asphalt mortar (CA) disengagement of a ballastless track will induce changes of dynamic response of a passing vehicle, which can accordingly be used to estimate the disengagement degree. In this paper, a novel method called CA mortar disengagement degree estimation algorithm (CMDEA) is proposed through an analysis of wheel acceleration of a ...

Mathematical Problems in Engineering, Volume 2017, Issue 1, 2017., 2017 A model based on the theory of train‐track‐bridge coupling dynamics is built in the article to investigate how high‐speed railway bridge pier differential settlement can affect various railway performance-related criteria. The performance of the model compares favorably with that of a 3D finite element model and train‐track‐bridge numerical model.
