Abstract

Abstract: To reduce the wear of pantograph and catenary system while decreasing the headway, the temperature field of the contact wire is studied. A simulation model is established by using the COMSOL Multiphysics software. The effectiveness of the model is verified with temperature experiments. Temperature field of the contact wire of freight locomotive and passenger locomotive in different intervals is studied by simulation. The smaller the headway of trains, the higher the temperature value, and the shorter the balance process. Under the constraint of temperature field, the headway of freight locomotive couldn't be less than 180s under long term operation. The interval of passenger locomotive couldn't less than 160s under operating speed and 140s under experiment speed. When the headway of trains is constant, the steady state temperature is lower at larger speeds. While steady state temperature is higher in larger currents. The temperature difference in one interval is similar under different speeds and large in different currents in stable operation stage.
