Abstract
This work consists of evaluating the impact of the most relevant characteristics of railway vehicles,
namely geometric, mechanical and aerodynamic properties, in their runnability in the presence of
strong winds, more precisely in the risk of derailment. Such objective is achieved by performing
several dynamic with a non-linear vehicle-structure interaction model developed by the authors
[1,2] and used in other works in this field [3,4], which allows the evaluation of the wheel-rail contact
forces and, consequently, the unloading index, as suggested by the European Norm EN 14067-6 [5].
The calculations are carried out for several scenarios characterized by different train and wind
speeds. The wind is simulated with a stochastic model that allows the generation of turbulent wind
time-histories based on power spectral density functions. The reference vehicle adopted in this work
corresponds to the European InterCity Express 3 (ICE-3) train, whose original properties were
parameterized to evaluate their influence in the vehicle’s stability. This parametric study focuses on
the variation of several properties of the vehicle that may influence its dynamic behavior against
crosswinds, namely the carbody mass, height of the gravity center, aerodynamic coefficients, and
stiffness and damping of the suspensions. Apart from the suspensions’ properties, which prove to
have a negligible influence in the vehicle’s stability, the remaining parameters have a significant
impact in the running safety against crosswinds.
