Analyzing the impact of curved tracks on wheel flange thickness reduction in railway systems
Open EngineeringFlanges are critical parts of railway wheels that guide the wheels on the track and prevent them from derailing. However, curved tracks have a great influence on wheel flange wear, which leads to increased maintenance costs, passenger discomfort, poor ...

A Numerical Model for Railroad Freight Car-to-Car End Impact
Discrete Dynamics in Nature and Society, 2012 A numerical model based on Lagrange-D'Alembert principle is proposed for car-to-car end impact in this paper. In the numerical model, the friction forces are treated by using local linearization model when solving the differential equations.
