Abstract
Résumé

This Note outlines the investigation of the water-based friction modifier used in railway technology. This investigation involves measurements made using a novel measuring stand, a new modelling of the modifier and the identification of its parameters using measured results. The proposed model of the modifier is composed of a dry friction slider, a dash-pot and a spring. The investigation contributes to a deeper understanding of the modifier's performance.

Cette Note présente l'étude expérimentale des propriétés mécaniques du modificateur de frottement sous forme d'émulsion d'eau, utilisé dans les chemins de fer. Le travail présente les mesures sur un banc d'essai moderne, la modélisation et l'identification des paramètres du modèle mathématique sur base des recherches expérimentales. Les éléments du modificateur sont les suivants : un coulisseau du frottement à sec, un ressort et un amortisseur visqueux. Dans la description du modèle ont été appliqués les éléments d'analyse mécanique rugueuse. Les résultats de l'étude permettent une meilleure compréhension des principes du travail du modificateur.
