Investigation into resistance forces from the wheel-rail interface of a four-axle railway vehicle in curved track

This study focuses on the resistance forces resulting from the wheel-rail contact in a four-axle railway vehicle operating on curved tracks of varying radii and quality.Using a dynamic simulation tool, the research analysed over 900 simulations to compute energy dissipation and specific resistance forces.The findings reveal that curve resistance decreases with larger curve radii, whereas deteriorating track quality leads to higher resistance and increased deviation.The results emphasize the significant impact of track quality on resistance forces, particularly for larger curve radii.Future research aims to refine regression models and explore the deviation reduction in resistance for small-radius curves.
