Abstract

Dynamic loads exchanged between the rolling stock and the operated track are intrinsic to the railway operation environment. The purpose of the authors is to trace a path towards a realistic definition of a load mission profile for the structural fatigue dimensioning of the vehicle components. In former works, the methodology to study how the varying characteristics of vehicle components, in normal and degraded conditions, can impact on the vehicle/track interaction loads and on the track damage, was widely dealt with. In this paper, the same methodology is applied to study the impact of modified track conditions on the vehicle/track interaction loads. The focus of this paper is therefore on the characterization of the track and its maintenance status, necessary to simulate the real loads experienced by the vehicle and by the track itself. The aim is to highlight what “indexes of health of the track” weight more on the dynamic loads exchanged between the vehicle and the track, and shall therefore be kept under control, to minimize safety risks and operational costs. The assessment criteria are defined according to the EN14363 regulation.
