Effect of Structural Flexibility of Wheelset/Track on Rail Wear

To investigate the influence of structural deformation wheelset and track on rail wear in longitudinal lateral directions, a prediction model is established that can calculate three-dimensional distribution wear. The difference between multi-rigid-body dynamic rigid-flexible coupled model, which considers flexibility track, compared terms results show distributions predicted by two models are relatively similar. There no obvious band, direction almost identical. cross sections worn shapes determined essentially same, with maximum 3.6% average value areas all sections. irregularity main reason for uneven direction. position where more pronounced hardly varies evolution It recommended to use wear, allows both calculation accuracy efficiency.
