The measurement of real wheel and track profiles, and their use in finding contact conditions, equivalent conicity, and equilibrium, rolling line (TN-DA-022)

"Equivalent Conicity" and "Equilibrium Rolling Line" are shown to depend on the cross-aectional profiles of both the wheelset and track. It has been found that very accurate measurements of the profiles, in digital form, are needed to calculate the values of the two parameters. A range of machines has been...
