RSFT-RBF-PSO: a railway wheel profile optimisation procedure and its application to a metro vehicle

Vehicle System Dynamics, 2021
With the expansion of urbanisation, more and more metro vehicles shuttle on dedicated railway lines, leading to serious wheel wear and reduced passenger comfort, it is therefore of interest to design a wheel profile that matches well with the dedicated ...

An investigation into the effect of resilient wheel stiffness on the dynamic behaviour of a metro vehicle running along a tangent track

Journal of Vibration and Control, 2022
Resilient wheels are extensively used for trams due to the noise reduction they can achieve. However, the effect of the resilient wheels on vehicle dynamics has not been adequately studied. An effort is presented in this paper, trying to bridge this gap.

Research on Impacting Loads between Metro Vehicles

Applied Mechanics and Materials, 2014
In order to research impacting characteristics of the trainset, the impacting model and governing equations are established, in which, the stiffness and nonlinear damping of a buffer, friction force between rail and the vehicles wheels is considered. The stiffness and nonlinear damping of the buffers used in the model is verified by testing results. By

An investigation into the fatigue failure of metro vehicle bogie frame

, 2020
Metro vehicle bogie frame is usually subjected to complex external excitations. The fatigue damage accumulation of bogie frame is induced by multiple elements and may even lead to failure hazard.

Soft Failure Analysis of Metro Vehicle Charger Circuit

Applied Mechanics and Materials, 2013
Failure prediction is of great significance for power electronics systems. Taking the metro vehicle charger circuit as an example, soft failures are discussed. The paper established the system simulation model through MATLAB/SIMULINK, and carried on spectrum analysis with POWERGUI module, and analyzed system output when the parameter changed.

Research on the Wheel Wear and Rolling Contact Fatigue of Metro Vehicle Induced by Rail Corrugation

Tribology Transactions
Rail corrugation is a common characteristic of track wear and exacerbates wheel–rail interaction and accelerates wheel wear and crack propagation. This study focuses on wheel wear and rolling contact fatigue of a metro vehicle under rail corrugation ...
