The Exploration and Research of CRTS I Slab Ballastless Track Used in the Freight Lines

Abstract:

The CRTSⅠslab ballastless track structure was the research object of this thesis and the truck vehicle-track dynamics coupled model had established in this thesis. Germany track interference spectrum was used as the track irregularity. The study analyzed the force conditions of the CRTSⅠslab ballastless track under the action of heavy freight trains in 110km/h, as well as the wheel-rail vertical force, vertical displacement and acceleration of the rail and rail board changes with time. The results show that the CRTSⅠslab ballastless track can meet the basic requirements of freight line.
