Ice coating on overhead contact system (OCS) will affect the sliding of pantograph and arc discharge
phenomena will occur between pantograph and catenary, which will threaten the normal operation of
train. At present, there are three different methods to equivalent the ice coating on OCS. The increased
density method, uniform load method and combinatorial material method of icing are used to analyze
the icing problem of pantograph-catenary (PAC) system. The dynamic response of the PAC system with
icing is compared and analyzed by different methods. The results show that with the increase of icing
thickness, the current collection quality of PAC system becomes worse.
