实测车轮踏面和钢轨间蠕滑系数的推算

Estimation of Creep Coefficient between Actual Wheel Profile and Rails

使用实测的车轮踏面形状进行轮轨接触区域分析,根据同一踏面内多点接触的条件推算蠕滑系数。同时利用分析模型,对3种蠕滑系数分析方法的效果进行了模拟评价。

The actually measured wheel profile is used to make the wheel-rail contact zone analysis. The creep coefficient is calculated on the basis of the multi-contact points conditions on the same wheel profile. In the mean time, with the analysis model, the simulation evaluation is made on the influence of the three creep coefficient analysis methods.
