山西中南部铁路通道发鸠山隧道改线方案动力学优化

摘要

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.%依托山西中南部铁路通道工程，建立车线系统动力学模型，选取典型区段线路设计方案进行全面的动力学评估。以发鸠山隧道改线方案原设计和优化后设计的线路平纵断面参数作为线路条件，对比30 t货车和客车通过时的动力学性能指标，给出适用于30 t大轴重的重载铁路圆曲线半径建议值，可供未来重载铁路线路设计参考。
