Study on wear law of 60 N rail based on UM-Ansys-MATLAB co-simulation
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％.
