The aim of the current paper is to assess the ability of active steering systems to prevent the development of rail corrugation in curves.

    For that, the corrugation growth rates obtained for a passive vehicle are compared with those obtained for active vehicles (in the current work two strategies for active steering are described and implemented: relative angle control and yaw moment control).

    The procedure for the calculation of the corrugation growth is described: first the quasi-static creepages produced during curve negotiation are calculated by means of a railway simulator program (SIMPACK) in different cases. Second, these obtained creepages are introduced in a non-linear corrugation model that evaluates dynamic variations in normal and tangential wheel rail contact forces. Finally, on the basis of these forces, the evolution of the rail profile is determined.

    The paper includes results of the selected control strategies that show the potentiality of active steering systems in reducing corrugation growth rates.
