Abstract:Research purposes: The test was done to the effects of axle load and curve radius on the rail wear vo lumeby using a JD - 1 wheel- rails imulation facility. Further more, the analysis was made for the effects of axle load and curve radius on friction work of wheel and rail under the same working condition with numerical programme CONTACT. Based on the test and calculation result the study was done on the relationship between rail wear volume and friction work and the preliminary empirical formula was offered for simulation calculating the wear volume of rail specimen by using friction work.
Research conclusions:The wear volume of rail specim en and friciton work of contact area of wheel and rail changes with the changes of the axle load and curve radius. There is a corresponding relationship between wear volume and friciton work of wheel and rail This study result offers a certain reference value to study ing rolling contact wear of rail in laboratory.
