전기철도 전차선로 부품의 3차원 디지털화 연구

초록

In electric railway, the OCS (Overhead Contact System) is designed in consideration of the material, shape, and wave propagation speed of the contact wire in order to supply electric energy stably to the railway vehicle. Although the Korean railway standards define electrical and mechanical characteristic values to ensure the safety of parts, it is difficult to confirm the manufacturing tolerances required for the assembly interface between parts and mutual assembly. Reliability of manufacturing tolerances is required for OCS products, and it is necessary to determine the connectivity with all part; also, study the reverse engineering process for the parts without drawings. Therefore, in this paper, 3D data of parts for the introduction of digital-based parts management system in the OCS was implemented. For digital data production, a 3D scanner was used to scan a swivel clip applied to a steady arm, and reverse engineering was used to produce 3D data. In addition, the data produced for the analysis of the ability to assemble of the parts and products using 3D printer were compared to confirm the conformity.
