| 摘 要： | 轮轨润滑是重载铁路减轻轮轨磨耗及损伤的有效措施之一。基于多体动力学理论,建立了配装不同类型转向架的C80B型重载车辆动力学分析模型,利用多点接触轮轨模型和轮轨接触摩擦功进行磨耗评价。计算得出了不同曲线工况下,轮轨润滑对交叉支撑转向架和径向转向架轮轨磨耗的作用规律。

| Abstract: | The lubrication is one of the effective method to reduce wheel-rail wear and damage for heavy haul railway.In this paper,the dynamics model of C80B type heavy haul freight car equipped with different bogies were established by MBS theory.the multi contact wear model and the friction work were used for assessing the wheel-rail wear.and the different influence law of lubrication on wheel-rail wear of cross-braced bogie and radial bogie under different curve negotiating conditions were obtained. |

| Keywords: | wheel-rail wear wheel-rail lubrication friction work cross-braced bogie radial bogie |
