Method of track vertical stiffness estimation based on experiment
Journal Title: Archives of Transport - Year 2010, Vol 22, Issue 2
Abstract
This paper presents a method of estimation of the track vertical stiffness changes based on the measured track vertical deflections during quasistatic railway vehicle motion along the track. Measurements of deflections were performed on the selected railway track section for applied static axle load of the wagon. The measured deflections were used to estimate track vertical stiffness variations. The courses of these variations were considered on the basis of two series of experiments (1st and 2nd stage) executed on the same track section at ten months long interval. In both stages of the experiment weather conditions were close to each other.
