abstract

This paper uses the finite element method to investigate the effect of rail corrugation on the wheel-rail thermal contact pressure and temperature distributions during wheel braking. Contact elements are used to simulate the contact between a wheel and a rail. Various friction coefficients, wavelengths and amplitudes of corrugated rails as well as braking times are considered in this study. The results indicate that, in the wheel-rail contact area, the rail corrugation affects the contact pressure and temperature distributions significantly. A modified equation with time-dependent heat partition factor is proposed to predict the rail surface temperature distribution for rails with smooth surfaces. Simulation results show that the proposed equation works very well. The results also indicate that the corrugated rail can lead to a wavy temperature distribution on the rail surface. Also, a smaller corrugated rail amplitude results in a higher maximum temperature near the trough region and a lower one near the crest region.
