Analysis of wheel-rail contact under partial slip and low speed conditions

The paper analyzes applicability of rolling contact simulation in low speed and adhesion conditions. Additionally, transition zone of the coefficient of friction (COF) is implemented. Effects of the COF are examined to the forces which are normal and tangential components. Various comparative studies are also computed. Differences between numerical results and results of the comparative studies are observed for validation. The results show that outputs of developed FEM model are compatible with comparative studies. Transition zone of the COF directly affects the traction force at low speed conditions.
