Study on the wheel/rail adhesion restoration and damage evolution in the single application of alumina particles

Popis výsledku v původním jazyce

The aim of this study is to explore the wheel/rail adhesion restoration performance of alumina particles and the comparison between the continuous and single application test strategies in twin disc simulation. The results indicate that the single application test strategy performs better on evaluating the adhesion restoring ability of solid particles. In the single application tests, the restored adhesion coefficient increases with the applied alumina quantity and final gets stable when the quantity exceeds 2 g (0.607 g/m). However, the increase of alumina quality could always extend the duration of restored adhesion. The alumina particles at the size in the range of 0.075–0.15mm showed the best adhesion restoration and the longest duration was achieved at the size of 0.15 mm. In addition, it is observed that the serious damage is mainly caused in the particles crushing process, and will be gradually ground off in the following long running to have no threat on the serving life of the wheel and the rail. and the rail.
