Modeling of the fatigue crack growth in a railway axle under random loading

Abstract

Purpose

The present paper aims to present a numerical modeling of a train bogie following a railway accident in the Algerian railway which clearly showed the presence of cracks at the level of the bogie axles.

Design/methodology/approach

Our approach consists of making a numerical modeling in dynamic under variable load taking into account the reality of several parameters.

Findings

The aim is to present a predictive model allowing the identification of the probable causes that are the cause of this premature deterioration. We have determined the lifetime and the influence of frequency on railway axle. Also, the influence of overload on railway axle. The numerical model will be directed by Ansys software.

Originality/value

Our study allowed us to understand the mechanical behavior of a railway axle under several loadings, and to determine the critical value of the final failure to avoid damage.
