THE EFFECT OF TWO POINT CONTACT ON THE CURVING BEHAVIOUR OF RAILROAD VEHICLES

This paper describes recent improvements in the prediction of wheel/rail forces. These improvements are associated with the analytic modelling of thee two point contact conditions that exist with the standard wheel and rail profiles in common use in the USA. Experimental results from tests on a rapid transit system highlighted the errors that existed in the previous single point contact analysis and provided a validation of the two predictions. the two point contact model predicts significantly larger wheel rail forces, higher wheel/rail wear and larger train resistance than would be estimated from a single contact point model.
