Abstract:   (820 Views)
Wheel-rail interaction has always been one of the issues in the railway industry. In this paper, the effect of Hertzian and non-Hertzian contact theories on the wheel wear due to the rail inclination was investigated. by using the UM software.
According to the results, longer contact areas are obtained in non- Hertzian contact theory compared to Hertzian contact theory. In non-Hertzian contact areas, the wear band and wear depth in the areas near the flange were decreased with increase rail inclination, while it was opposite in Hertzian contact areas.The distribution of wheel and rail contact points in the Hertzian contact is scattered in the final wheel profile, while in non-Hertzian contact the accumulation of the contact points is observed.
