Abstract:
The present paper is about the numerical modelling of a weight-in-motion system developed with the aim of assessing the static loads imposed by the train to the track infrastructure. The presented WIM system constitutes a part of a larger project PEDDIR dedicated to the Portuguese acronym for weighing in motion and wheel defect detection system. In order to overcome disadvantages due to of costs and traffic management typical of conventional static weighing, such system could be convenient. This study focuses on numerical parametric studies as about the prone influence of speed, rail pad properties, foundation properties, and track unevenness profile on train dynamic load by one hand and on the accuracy of the access mean of the static load from the dynamic measurements.
Keywords:
Weigh-in-motion systems (WIM) , track overweight , train speed , rail pad stiffness & damping , foundation stiffness & damping , rail unevenness
