This paper features a method of synthesizing the track irregularities by which the alignment may be analytically represented by a pseudo-stochastic function, as well as the implementation of such a method in the numerical simulation of the dynamic behaviour of the railway vehicles. The method described in Part I relies on the power spectral density of the track irregularities, as per ORE B 176 and the specifications included in UIC 518 Leaflet regarding the track’s geometric quality. Part II shows the results of the numerical simulations regarding the lateral behaviour of the railway vehicle during the circulation on a tangent track with lateral irregularities, synthesized as in the method herein. These results point out many basic properties of the lateral vibration behaviour of the railway vehicle, a fact that demonstrates the efficiency of the suggested method.
