title = "An Iterative Approach for Analyzing Wheel-Rail Interaction",
abstract = "The steady-state vehicle-track interaction or the interaction of the moving train with rail defects may result in unstable vibrations. The interaction of the moving train with such track defects induces additional dynamic stresses in the track system that may prove harmful for the structural health of the track. In this paper, a new iterative approach is proposed for analyzing the coupled equations of the vehicle-track system. The proposed approach can account for the wheel/rail contact loss. The results show that the proposed approach is computationally efficient and can be employed to study the effect of a wide range of track defects on the vehicle-track response. As an example, the vehicle-track response is obtained for the case where the wheel is traversing a rail-head corrugation. A loss of contact is observed when the wheel encounters the rail-head corrugation. The wheel-rail contact loss results in high impact loads over the rail beam leading to a sudden increase in rail beam deflections (by up to 85\% and 57\% for the undamped and damped cases, respectively).",
