1. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance
Abstract : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. READ MORE
