Dynamics Simulation Model of Pantograph and Conductor Rail in Electrified Railway and Its Application

Overhead conductor rail which has become the main form of the overhead catenary, is widely used in low headroom tunnels. In order to understand the vibration behavior of pantograph and conductor rail, it is necessary to carry out the study of the interaction between pantograph and conductor rail. In this paper, we will present a dynamic simulation model of the contact force between a pantograph and a rigid catenary. The contact point change matrix with time and the calculation procedure of contact force will be given. Finally, applying the dynamic simulation model, the dynamic response and the maximum limit speed of conductor rail have been analyzed.
