Abstract

Abstract

In order to reflect really wheel-rail contact states, the displacement, bouncing, yaw, roll of wheelsets and the displacement, bouncing, roll of rails were considered, wheel-rail normal forces at two contact points were respectively calculated by nonlinear Hertz contact theory, the minimum gap between rail and wheel was calculated by trochoid method and divided rail outline method, so that wheel-rail real contact states, such as natural one-point contact, nonnatural one-point contact, two-point contact and wheel complete lift, were easily judged.Simulation result of wheel-rail contact relation shows that judged wheel-rail relation accords with real wheel-rail contact relation, the method is feasible.
