A Study of the Effect of Global Track Stiffness and its Variations on Track Performance: Simulation and Measurement
2009 (English)In: International Heavy Haul Conference: Shanghai 2009, 2009Conference paper (Refereed)
This paper investigates the effect of vertical track stiffness, and its variations along the track, on track performance with focus on dynamic responses of track due to parametric excitations. Two approachesfor calculating global track stiffness, a static one based on Zimmermann’s theory, and a dynamic one basedon the track model used in the dynamic vehicle-track interaction program DIFF, are discussed. A RollingStiffness Measurement Vehicle (RSMV) has been developed at Banverket and measurements have been carried out over hundreds kilometre long tracks. This paper presents a statistical analysis of the collected results and provides information of track stiffness and its variation on typical Swedish tracks.
