Wear Rate Analysis Of Overhead Line Contact Wire By Considering Current Effect Using Ansys.

The overhead line and pantograph is the two contacting bodies Wear on overhead line is one of the greatest problems in the railway industry. To overcome the problem of wear on overhead line different studies have been made. A better material selection that can withstand material loss due to sliding is the major solution that has been carried out but the effect of electrical force together with mechanical load is still challenge. In this research, the combined effect electric field and mechanical load is considered on wear of overhead line. In order to analyses overhead line wear rate the electric field effect due to the operational current and mechanical load effect has been under consideration. The modeling of pin-on-disc is made in CATIA software, the structural analysis is done using ANSYS workbench. The structural analysis is then used the stresses of the material of pin. In this cases, the applied load increases with operational current increases then the equivalents stresses increases. The wear rate increases with the operational current increases, so the better material in this researcher is the CuNiCr material because it has good wear resistance. Finally, this paper suggests this material to be used for contact wire material.
