曲线轨道参数对轮轨磨耗的影响

Effects of Curve Track Parameters to Wheel/Rail Wearing

本文将车辆和钢轨考虑为耦合体,建立了十三个自由度的货车稳态曲线通过模型,详细讨论了曲线轨道参数对货车曲线通过时轮轨间的横向力、轮缘力、冲角及磨耗指数的影响,为曲线轨道参数的合理选取提供参考。

In consideration of track and vehicle as a coupling body, a steady-state curving mechanical model for freight train car, which has 13 degrees of freedom, is established in this paper. The influence of curve track parameters to lateral force, flange force, yaw angle and worn index of wheel/rail is studied in detail when the freight car is through a curve track. All of these can provide reference for suitable selecting curve track parameters.
