The impact wear behaviour and damage mechanism and transitions of rail weld joint and rail materials were explored using a cyclic impact tester under dry conditions. The results indicate that the impact wear volume of rail weld joint and rail material increases with the number of impact cycles or impact force increasing and the resistance to impact wear of rail weld joint is better than that of rail...
The objective of this paper was to investigate wear and damage behavior of heavy-haul railway rail. Furthermore, the mechanism and preventive measures of heavy-haul rail damage were explored in detail. The results show that the rail side wear and surface spalling are dominating damage mechanism for Datong-Qinhuangdao heavy-haul railway. With the annual transport volume increasing, average wear volume...
