Abstract:Innovative non-contact sensing and monitoring systems based on Vision-Based (VB) technology are becoming a viable method to remotely capture railway track vibrations and quality. This paper describes the use of VB system for the measurement of track vertical displacements and the estimation of track stiffness. The dynamic response of the track under a moving vehicle load was investigated through experimental and numerical modelling using a series of large-scale trails and finite element (FE) simulations. The a… Show more
