摘要：The wheelrail 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 wheelrail contact forces. However, most of them tackle this problem purely from a theoretical point
of view and need to be experimentally validated. Such validation could also reveal
the influence of certain parameters not taken into account in the mathematical developments. This paper
characterisepresents the steps followed in building a scaled test-bench to experimentally characterise the wheelrail contact problem. The results of the longitudinal contact force as a function of the longitudinal creepage are obtained and the divergences with respect to Kalker''s simplified theory are analysed. The influence of lateral creepage,
