This paper features a method to synthesize the track irregularities, by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method thus suggested allows a convenient formulation of the limits of the interval specific to the wavelengths of the track lateral irregularities, so that it will be representative for the frequency range of the vehicle lateral vibrations. The Part I of this paper demonstrates the method to synthesize the track alignment and its basic elements –the power spectral density of the track irregularities, as per ORE B176 and the values associated with the track quality levels, mentioned in the UIC 518 Leaflet. The Part II introduces the results of the numerical simulations regarding the dynamic behaviour of the railway vehicle during the circulation on a tangent track with lateral irregularities, synthesized as in the method herein.

L’article présente une méthode pour la synthèse des irrégularités de la voie, aveclaquelle le dressage peut être représenté analytiquement par une fonction pseudoaléatoire et aussi l’application de cette méthode dans la simulation numérique du comportement dynamique latérale des véhicules ferroviaires. La méthode proposée permet de choisir convenablement les limites d’intervalles spécifiques des longueurs d’onde des irrégularités latérales de la voie, de sort qu’elles sont représentativespour le domaine de fréquence de la vibration latérale du véhicule. La Partie I de l’article, analyse la méthode de synthèse du dressage de la voie et donne ses éléments de base –la densité spectrale de puissance décrite conformant ORE B176 et les quantités associées de la voie précisées dans la Fiche UIC 518. La Partie II présente les résultats des simulations numériques du le comportement dynamique latéral du véhicule pendant la circulation sur une voie en alignement avec des irrégularités latérales synthétisées en utilisant la méthode présentée.
