Stress/Strain analysis in the bogie in linear motion

Abstract

Abstract The railway wheel, together with the axle, represents one of the very important parts that support the safe operation of railway vehicles. Wheels support the entire weight of cars. Therefore, the reliability is demanded in terms of accuracy. Accordingly, the most important and fundamental characteristic in designing wheels is strength. The investigation of dangerous area in bogie is one of important area of study in railway manufactured. This essential information is required in structural integrity, failure and fatigue calculation to determine lifetime for scheduling the maintenance and regrinding necessity. The aim of this work is to determine the stress/strain in a bogie to common working in operating conditions using the 3D finite element method (FEM). The FEM results carried out using 3D elements allows the stress/strain distribution with good accuracy. Knowing the maximum stress/strain value in a bogie, prevents an unsafe construction from the design stage, and consequently increases safety in rail traffic.
