The paper focuses on evaluating the stability of the railway vehicle during running on a track horizontal irregularities and investigating the possibilities to improve the dynamic behavior on a lateral direction. The evaluation method for the stability relies on the homologation specifications of the railway vehicles from the perspective of the dynamic behavior included in the UIC 518 Leaflet, where the lateral accelerations of the bogies represent evaluation units for the stability. The lateral accelerations are derived from numerical simulations, developed on a non-linear complex model of the vehicle/track system, where the vehicle is described by a mechanical system with 21 degrees of freedom. The results thus presented outline the possibilities of improving the vehicle stability by adopting the best values of the lateral damping of the secondary suspension or of the lateral stiffness of the primary suspension that will lead to the minimizing of the lateral acceleration in a bogie.
