摘　　要：为了研究轮轨型面对重载货车曲线通过性能的影响,选择我国LM车轮踏面与75kg/m钢轨(简称CN75)、美国AAR-1B踏面与136RE(即68kg/m)钢轨、欧洲S1002踏面与UIC60钢轨,比较了这3组轮轨型面的几何形状和轮轨接触几何关系.基于Adams/Rail建立了C80BH货车的动力学模型,仿真计算了三种踏面在原配合状态时以及与我国75kg/m配合时C80BHBH货车的曲线通过性能,比较了轮轨横向力、脱轨系数和轮轨磨耗等参数.结果表明:AAR-1B踏面与CN75钢轨配合在半径400m小曲线上具有较好的曲线通过性能;LM踏面与CN75钢轨配合在半径800米曲线上的轮缘磨耗较小;曲线上,S1002踏面和CN75钢轨配合的轮轨横向力出现剧烈振荡.Three sets of wheel / rail profile are chosen,suchas Chinese wheel profile LM and track 75 kg / m（ CN75）,American wheel profile AAR-1B and track profile 136RE（ 68 kg /m）,and European standard wheel profile S1002 and track profile UIC60,to compare their profiles and interaction of geometric contact.The curving performance of C80 BH freight cars,such as the parameters of lateral wheel-rail force,derailment coefficient and wheel-rail wear,is simulated when the three wheel profiles match their corresponding track profiles and Chinese 75 kg / m rail. Results show that,on the curve of radius 400 meters,the curving performance of AAR-1B matching CN75 is well. On the curve of radius 800 meters,the wheel flange wear of LM matching CN75 is less. The lateral wheel-rail force of S1002 matching CN75 has strenuous oscillation.
