Abstract |
This study performed thermal history simulation and strategy optimization for additive manufacturing of eye-shaped catenary clamps used in high-speed railway overhead lines. Instead of the conventional casting material CuAl10Fe2, SUS 316L material suitable for additive manufacturing and having good toughness was used. The thermal analysis simulation software for additive manufacturing was utilized to optimize the additive manufacturing strategy for the parts where heat diffusion was not sufficient. The optimized additive manufacturing strategy was verified by simulation while adding supports, and the accuracy of the simulation was confirmed by comparing the simulation results with the actual experimental results. The results of this study can provide useful guidelines for additive manufacturing of eye-shaped catenary clamps and can be applied to other parts with complex shapes. |
