Abstract


The paper analyzes applicability of rolling contact simulation in low speed and adhesion conditions. Additionally, transition zone of the coefficient of friction is implemented. Efffects of the friction coefficient are examined to the forces which are normal and tangential components. Various comparative studies are also computed and differences between numerical results with 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 coefficient of friction directly affects the traction force at low speed conditions.
