Continuous measuring method of the resistance to lateral displacement of a railway track

摘要

The measuring system uses an oscillation generator (21) for causing the tested rail track to oscillate in a horizontal direction, transverse to the track longitudinal direction, with measurement of the operating power for the oscillation generator, as an indication of the transverse displacement resistance of the track. Pref. the pressure of the hydraulic operating fluid used to drive the oscillation generator is measured as an indication of the transverse displacement resistance of the track, pref. with auxiliary measurement of the oscillation frequency and/or amplitude, the vertical loading force acting on the oscillation device (12) and/or the displacement rate of the track testing machine.
