Abstract

This paper extends the modelling approach towards the evaluation of wear, by including the effect of rail/wheel hardness ratio and ambient temperature. We firstly perform wear tests in the laboratory with varied hardness ratios from 0.79 to 1.60, and different ambient temperature from -40 to 20 degree. Then we formulated the new wear laws and determined corresponding coefficients in the formulas. The proposed new wear laws are validated through a numerical example based on a prediction model. Comparison between the simulated results and in-field results shows that the results from the simulation are well consistent with those from field measurements.
