The development of numerical models able to compute the wheel and rail profile wear is
essential to improve the scheduling of maintenance operations required to restore the …

The reliability analysis of engineering structural systems with limit state functions defined
implicitly by time-consuming numerical models (eg finite element analysis structural models) …

Wear in rolling contact is a complex phenomenon because it is multi-scale and multi-
physical by nature and involves many strongly correlated parameters. It makes the …

Wear of wheel profiles is a common degradation process that significantly impacts the
reliability of wheelsets. In this study, a conditional bivariate Gamma process is constructed to …

The accuracy of physics-based wheel wear prediction approaches depends not only on the
vehicle-track dynamics model but more importantly on the wear model. The currently …

The aim of this paper is to accurately predict the evolution of wheel profile wear and related
vehicle dynamics for high-speed trains by considering the stochastic wheel/rail interactions …

Railway crossings are subjected to a severe load environment leading to damage and
degradation of rail profiles. The damage is the result of the high magnitudes of contact …

Wear modelling of train wheels has long been an important research topic; both physics-
based and data-based methods have some weaknesses. To bridge the gap between them …

Wheelsets absorb a significant part of the maintenance budget of any train operating
company. Although wheel wear has been an extensively discussed topic in the literature …

In this article, we propose a practical prognosis approach. It estimates online the remaining
duration of the system before the system performance requirements are no longer met to …
