Abstract:
An on-board, non-contact measurement system and method is disclosed for measuring track quality, vertical track stiffness and vertical track modulus for a portion of track underlying the rail vehicle. The system comprises two or more position sensors for determining the position profile of the track and a computation system for determining the vertical displacement of the track.
