摘　　要：NEFA706型踏面是阿根廷地铁客户推荐采用的,通过与国内常用的LM型、LMA型和S1002型踏面的踏面外形、轮轨接触关系(54E1型钢轨)、轮轨接触应力和动力学性能(特定参数条件)进行对比分析,得出这4种踏面型式分别与54E1型钢轨匹配时的性能结果,为出口阿根廷地铁车辆车轮踏面的选取提供了理论依据。Comparative analyses are conducted between domestic LM, LMA, S1002 wheel treads and NEFAT06 tread recommended by Argentine customer in terms of tread profiles, wheel/rail （54E1 rail） interaction, wheel/rail contact stresses and dynamic properties （under specific parameter conditions）. The studies reveal the performances of these four tread profiles when matching 54E1 rail, which lay a theoretical basis for the selection of wheel tread profile for the metro cars to be exported to Argentina.
