| Abstract: | A lateral dynamic analysis model for the track is described in which the rails are regarded as beams on lateral multiple elastic supports, with the elasticity and damping of the fattenings and ballast taken into account. The contact locations between the wheels and rails and the flange frictional work are computed with the help of the spacial contact theory. The wear indices are discussed and revised. |
