This paper analyses the lateral dynamic behaviour of a four-axle freight wagon with Union Internationale des Chemins de fer (UIC) single-link suspension where dry friction is used to damp oscillations. Mathematical models of the standard UIC single-link suspension have been prepared elsewhere according to non-smooth mechanics assumptions and implemented into established MBS programs. Numerical simulations of the motion of the four-axle freight wagon with a 200 kN static axleload have been performed on straight track according to methods appropriate for predicting the dynamic stability of freight wagons.
