Prediction of Contact Temperature on Interaction between Rail and Wheel Materials Using Pin-on-Disc Method

Windarta, M. Bin Sudin and M.B. Baharom
The interaction between rail and wheel materials produce wear damage on each surface and frictional heat. This study is aimed to predict contact temperature due to the interaction between rail and wheel for various applied load and velocity. The frictional heat was modeled as a solid contact pressure. The temperature rise was calculated by numerically integrating the equation using Adomian Decomposition Method. The paper also studies the influences of sliding speed on temperature rise. The pin-on-disc experiment was used to validate the results. The results show the peak pressure distributions increase linearly with the increasing applied load with an average slope of 0.053. The maximum temperature rise was 259.98 K at x = 1 mm for 5.3 MPa pressure and 3.14 m sec-1 sliding speed. Prediction temperature rise results were successfully validated using pin-on-disc method. The average error between prediction and measurement results was 4.99 %.
