摘要：

用数值计算方法详细分析了轴重和车辆行驶时的曲线半径对轮轨接触质点总滑动量和摩擦功的影响。通过与模拟实验所得钢轨试样磨损量的数据对比发现：轴重和曲线半径是影响钢轨滚动接触磨损的重要因素；钢轨磨损量的变化与轮轨接触斑摩擦功间存在一定的线性关系。结合实验与计算结果初步得出了利用摩擦功模拟计算钢轨试样磨损量的经验公式，对进一步研究轮轨磨损问题和预测钢轨磨损量有参考价值。

Abstract:

The effects of axle load and curve radius on total slippage of contact particles and friction work of wheel/rail were investigated with numerical methods .Comparing with the date of rail wear volume tested by simulation experiments, it is indicated that axle load and curve radius are the important factors to effect rolling contact wear of wheel/rail, and there is a linear relationship between rail wear volume and friction work of wheel/rail. The preliminary empirical formula between wear volume of rail sample and friction work is given by analysing the experimental and calculation results, the formula offers a certain reference value for researching wear of wheel/rail and predicting wear volume of rail.

Key words: wear of rail/wheel, friction work of wheel/rail, axle load, curve radius
