Simulation, Development and Field Testing of a Track StiffnessMeasurement Vehicle
2005 (English)In: 8th Interntaional Heavy Haul Conference, Rio de Janeiro, 2005Conference paper (Refereed)
A new vehicle for continuous measurement of vertical track stiffness has been built by Banverket. Two oscillatingmasses of the vehicle excite the track dynamically and the track stiffness is calculated from measured axle box forces andaccelerations. The stiffness is given as a complex quantity and presents both the magnitude and the phase. The repeatability isvery good, and some promising results for soft subsoils are shown. Both overall measurements at higher speeds (up to 60km/h) and detailed investigations (below 10 km/h) can be performed.
