Use of Active Steering in Railway Bogies to Reduce Rail Corrugation on Curves

This paper assesses the ability of active steering systems in preventing the development of rail corrugation in curves. The research compares the corrugation growth rates of a passive vehicle and an active vehicle, using two active steering strategies -- relative angle control and yaw moment control. A railway simulator program (SIMPACK) is used to calculate the quasi-static creepages that are produced during curve negotiation. These creepages are then placed into a non-linear corrugation model, which evaluates dynamic variations in both normal and tangential wheel rail contact forces. Data results from these forces determine the evolution of the rail profile. Also included in this research are results of selected control strategies showing the potential for corrugation growth rate reduction within active steering systems.
