Abstract

Abstract

With the theory of vehicle-track coupling dynamics and the simulation softwareTTISIM, dynamic performances of vehicles with the cone and the worn profiles, respectively, are calculated and compared in detail. The results showthat the worn profile wheels perform better on curve tracks, while the cone profile wheels have higher critical speed of hunting stability. There is not obvious difference in carbody vibration of vehicles with the two type profiles running on tangent tracks.
