Information modelling of track geometry
Journal of Physics: Conference Series, 2020 Abstract The objective of this study is to substantiate a new method for modelling the railway track geometry. The method includes a new way of path measuring and the resulting method for modelling of track geometry. There can be two variants of track measuring with the new method. The first variant includes measuring only the lengths of

Establishment of Track Quality Index Standard Recommendations for Beijing Metro
Discrete Dynamics in Nature and Society, 2015 Since 2007, Beijing Metro started to use track geometry car to measure quality of its tracks under wheel loading conditions. The track quality measurement data from the track geometry car were only used to assess local track quality by means of scoring ...

Black-hole horizons as probes of black-hole dynamics I: post-merger recoil in head-on collisions
, 2012 The understanding of strong-field dynamics near black-hole horizons is a long-standing and challenging prob- lem in general relativity. Recent advances in numerical relativity and in the geometric characterization of black- hole horizons open new avenues

Track stiffness and the vertical track geometry deterioration modeling [PDF]
, 2012 Krutost šinske podloge je osnovni parametar konstrukcije gornjeg i donjeg stroja železničke pruge koji utiče na nosivost, dinamičko ponašanje vozila, kvalitet geometrije koloseka i vek trajanja elemenata konstrukcije. U radu se krutost šinske podloge razmatra sa aspekta modeliranja propadanja vertikalne geometrije koloseka.
