Abstract
There are many reasons for affecting of the freight train disc properties. The braking system
failures takes lion’s share of to affect the brake disc in operation. Under normal condition the disc
should have enough thermal capacity so that they can handle the heat developed by friction during
normal braking action. However, in any braking components failures the braking force will be
uncontrolled. Therefore, this thesis deals with the effects of uncontrolled braking force on
thermomechanical propertied of discs.
Particularly this paper emphasis on the effect of uncontrolled brake force on brake disc
which is created due to overcharging and losses of air in braking components. The purpose of the
study is to show, how the brake disk is affected its performance (thermomechanical properties)
due to uncontrolled brake force. At the end, this thesis helps to give a true picture to Ethiopian
Railway Corporation (ERC) about pri maintenance on the braking components before any
operation. Since any failures of braking system has effects on braking action and it has a
consequences on disc performance.
In the analysis a three dimension finite element model of the brake disc is used to investigate the
effects of uncontrolled braking force due to service braking. The specimens are modeled by
CATIA V5 R19 and analysis is done by ANSYS 12 and by imposing the uncontrolled forces.
The findings of this analysis will observed from ANSIS solution and give conclusion based on the
design standards and finally ended with recommendation.
