Systematical Analysis of Rail Corrugation in Urban Rail Transit

Journal of Convergence Information Technology, 2013
Abstract Rail corrugation is an adulatory wear which is similar to wave in shapes that can be observed on the rail rolling surface along the longitudinal direction after the rail is put into use. In this paper, a vehicle-track coupled finite element model is established to analyze the reason of rail corrugation systematically in urban rail transit. The

Influence factors analysis of rail potential in urban rail transit

Microelectronics Reliability, 2018
Abstract Rail potential is affected by a variety of influence factors in the urban rail transit. This paper proposes a state space average (SSA) model of the traction power system to explore the effects caused by the traction network resistance, inductance, capacitance and rail-to-ground resistance.
