ABSTRACT

To address challenges in railway curve section track replacement operations- including difficulties in longitudinal movement of old rails, limited space for new rail placement, and poor stability of welded rails-this study designs a longitudinal rail relocation system for curved track sections. Through 3D modeling and static simulation, beam element models of 60kg/m rails were established with varying lengths (50m, 75m, 100m, 150m), material properties were configured, and constraints and loads were applied. The analysis revealed support arrangement schemes for each rail length that ensure maximum deformation remains below 32mm. The system incorporates longitudinal rail movement mechanisms, positioning devices, and rapid disassembly components, enabling safe fixation of relocated rails while reducing cutting and secondary welding processes. This innovation enhances operational efficiency, cost-effectiveness, and safety in rail replacement for curved track sections, providing technical support for modern track maintenance practices.
