PREVENTION OF THERMOMECHANICAL DAMAGE OF WHEEL–RAIL TRIBO-SYSTEM WHEN SKIDDING

Abstract

Some tribo-thermodynamic hypotheses that permit to identify athermal and (or) thermal gripping, to define peak magnitude of the contact temperatures on the actual contact area of the wheel-rail tribo-system, are proved.
