Wheel–rail contact: experimental study of the creep forces–creepage relationships [PDF]
Vehicle System Dynamics, 2014 [EN] The wheel rail contact problem plays an important role in the simulation methods used to solve railway dynamics problems. As a consequence, many different mathematical models have been developed to calculate wheel rail contact forces.However, most of them tackle this problem purely from a theoretical point of view and need to be experimentally ...
