| Abstract: | Based on Shanxi central southern railway corridor, a vehicle / track dynamics model is established to conduct a comprehensive assessment of typical line sections. Taking the flat profile parameters of the original design and the optimized design as boundary condition, the dynamics performances of vehicles of 30 t wagon and passenger car passing through these railway locations are compared and applicable circular curve radius for 30 t axle load heavy haul railway is recommended,which may be used as reference for future heavy haul railway design. |
