中文摘要：

为了深入研究轮轨接触几何关系,针对国内铁道客运车辆车轮的4种典型踏面LMA、S1002CN、LM和XP55,采用简化法、谐波法、UIC519算法分别计算其等效锥度;编制一套轮轨接触关系软件TPLWRSim,与国际通用的多体系统动力学分析软件SIMPACK和ADAMS计算的结果相对比,在不同轮轨关系计算工况下,给出用3种软件计算的4种标准踏面的等效锥度表,为新型踏面设计提供参考.通过比较不同算法的优越性,表明谐波法和UIC519能更准确地计算等效锥度.同时,给出4种踏面的轮轨接触特征,为实际线路车轮磨耗跟踪试验时分析车轮磨耗行为提供参考.这些轮轨接触特征在实际车轮磨耗跟踪试验中得到了验证.

英文摘要：

For domestic railway passenger cars,the equivalent conicities of new wheel pairs with four typical treads LMA,S1002CN,LM and XP55 were calculated respectively with the simplified method,harmonic method and UIC519 method.TPLWRSim Software was developed to calculate equivalent conicities under different wheel-rail interaction calculation conditions and drawn into tables and the results were compared with the international general software SIMPACK and ADAMS.It shows that the harmonic and UIC519 calculations are more accurate.The illustrations of the wheel-rail contact characteristics of the four typical treads provide reference for new tread design and for analysis on wheel wear behaviour in wheel wear tracking tests on real railway lines.The wheel-rail contact characteristics are verified in real wheel wear tracking tests.
