Abstract

The icing problem of catenary is becoming more and more prominent with the expansion of the distribution range of rail transit lines. Ice coating on catenary will affect the sliding of pantograph and the power supply quality of train. In serious cases, the phenomenon of arc tension between catenary and pantograph will also occur, which threatens the normal operation of trains. The equivalent density method and the uniform load method of icing are studied to analyze the icing problem of pantograph-catenary system. The similarities and differences between the two simulation methods are compared. The pantograph-catenary dynamics simulation analysis is carried out based on the multi-rigid body model of pantograph. The results show that the icing of catenary will affect the current collecting quality of pantograph-catenary system. The difference between the two models in calculating the dynamic response of pantograph-catenary system after icing becomes obvious with the increase of icing thickness, and the mechanism of the difference is analyzed.
