In order to simulate the dynamic behavior of pantograph/catenary system accurately, a complicated simulation model in vertical is set up, in which not only the pantograph and catenary are included, but also the locomotive and track with irregularity are considered. Based on setting up the model, the dynamic behavior of pantograph/catenary system under condition of China railway system is studied. The parameters of catenary such as length of span, structure height and tension, and structure type of catenary with simple stitched wire or elasticity stitched wire are analyzed. In this paper, the effect of the presag of contact wire on current-feeding is studied, and the reasonable presag is proposeded. The irregularity of contact wire is firstly considered, and its influence on contact force is investigated. In order to improve the dynamic behavior of pantograph/catenary system, the parameters of pantograph such as stiffness, damping and mass are analyzed.
