| description | Utilizing the multi-body dynamics software Simpack, a dynamics model was established for an articulated hot metal ladle car. The axle load distributions across different articulated positions were obtained from both theoretical calculations and simulations. Based on a comparative analysis the curve passing performance of the hot metal ladle car at different articulated positions, the optimal articulation position was determined, taking into account the axle load distributions, and the nonlinear critical speed of the hot metal ladle car at this optimal articulation position was verified. Further exploration was conducted to investigate the influence of line parameters, such as track irregularities and curve radii, as well as operating speeds on the operational safety of the car on small-radius curves. The results indicate that the optimal articulation position can be attained when the longitudinal distance from the center of the bolster spring to the first position wheelset's center is half of that to the articulation point at the rear arm of the middle axle box, ensuring a balanced load distribution among the car axles and the optimal curve passing performance. The nonlinear critical speed of the hot metal ladle car is identified to be 40 km/h, which meets the operational requirements with a safety margin. Moreover, track irregularities exert a significant influence on the operational safety performance indexes of the car on small radius curves, followed by curve radii. In contrast, the influence of curve superelevation is found less significant. Meanwhile, operating speeds are chosen to ensure operational safety under different track irregularity and curve radius conditions. |
