摘　　要：采用UM-Ansys-MATLAB联合仿真技术,建立60 N新性能钢轨磨耗预测模型,仿真分析运营参数和轨道结构参数综合影响下60 N新性能钢轨廓形磨耗规律,并与U75V 60 kg/m钢轨进行对比,提出最优轨道参数建议值。仿真结果表明:轨底坡设置为1∶20、轨距加宽2 mm、外股钢轨欠超高约15%时,采用60 N新性能钢轨可延长重载铁路小半径曲线钢轨使用寿命约50%。Using UM-Ansys-MATLAB co-simulation technology,a 60 N new performance rail wear prediction model is established.Influence of operational parameters and track structural parameters on the wear behavior of 60 N new performance rails is analyzed and compared with the U75V 60 kg/m rails.The recommended values of optimal track parameters are proposed.The simulation results indicate that 60 N new performance rails in small radius curves can extend the rail service life of heavy haul railway by approximately 50%,when the optimal rail cantis 1∶20,the gauge width is 2 mm,and curve super-elevation setting is 15%.
