Abstract

The high temperature in sliding contact zone of a pantograph catenary system will cause wear of the friction pair

decrease the current-accepting quality of the system

or even induce break accident of the contact line. In this paper

the temperature field of the pantograph catenary system’s sliding contact area is analyzed

and the factors influencing the temperature field are investigated. The simulation software COMSOL is adopted to simulate the pantograph catenary system

a three-dimensional finite element model is established

and the experimentally measured data are used to verify the accuracy of the proposed simulation model. Subsequently

the effects of current

pressure

speed

and slide plate material on the temperature of the contact zone are obtained. The temperature in the contact zone increases with the increase in current and speed

and the temperature presents a U-shape change with the increase in pressure.
