Abstract:
The Effects of Top of Rail Materials and Rail Grinding on Head Hardened Rail
There have been studies of the current effects of top of rail materials and lubricants using twin disk testing. This study will build on previous research and attempt to create a more real world approach on rail by simulated grinding on head hardened rail steel. A twin disk apparatus will be used to simulate the effects of the wheel and rail interaction. After a set number of cycles the disks will be re-machined to remove surface level cracking thus simulating a grind cycle.
