Research project for an innovative concrete sleeper
Customer: Swiss Federal Office for the Environment, Switzerland
Experimental modal analysis on different concrete sleepers
Computational modal analysis FEM
Measurements in specially built test track
Measurements of TOR and sound radiation
Design and analysis of two sleeper types
Manufacture of sleepers by project partners
The new concrete sleepers were developed in cooperation with the Swiss concrete element manufacturer Vigier Rail. The existing sleeper types were first examined and analyzed using measurement technology and the parameters influencing the acoustics were analyzed.
With this research project on an essential element of the track superstructure, PROSE wants to advance the industry – with less noise and simultaneously low wear and tear or lower life cycle costs. This benefit both the affected residents and the infrastructure contractors.
