The Influence of Wheel/Rail Contact Conditions on the Microstructure and Hardness of Railway Wheels

Table 1

Inputs to Vampire dynamic simulations.

Vehicle model	Based on manufacturer’s data and validated against static and dynamic test results
Track geometry	68 km route measured by track recording car
Wheel profiles	9 wheel profile pairs measured from the vehicles in varying wear states (new to prereprofiling)
Rail profiles	8 measured rail profile pairs from the route, applied according to curve radius band
Wheel/rail friction	Top of rail considered dry; flange face friction reduced locally at track-side lubricator locations
Speed profile	Based on on-train data recorder information
Traction and braking forces	Based on on-train data recorder information
