A study on the cause of uneven wear of the catenary in the curved section of the R-bar catenary

Ho-Ryung Cho, Jeong-Il Youn, Jae-Moon Kim

Abstract

In this paper, we analyzed the contents of foreign data on the causes of abnormal wear and wear characteristics of the R-bar rigid catenary. Also, compared the general straight section, compared to the general straight section, it was confirmed that the contact wire in the curved section of the R-bar rigid catenary was replaced early due to uneven wear. After examining the case of early replacement, in order to confirm the case where the pantograph and the catenary are in slanted contact due to the effect of rail kent in the partial wear section of the catenary in the curved section of the domestic underground rigid catenary, the contact image of the catenary and the pantograph in the curved section of the rigid catenary The part identified by photographing will be described.
