Analysis the effect of unequal force application on A.A LRT disc brake during emergency brake
Biniyam Belayneh
A train disc brake system is used to perform three basic functions, i.e. to reduce speed of a vehicle, to
maintain its speed when travelling downhill and to completely stop the vehicle. During these braking
events, the disc brake may suffer of temperature, deformation and stress issues. It is quite sometimes
that the disc brake components fail structurally and/or having severe deformation on the pad. Thus,
this paper aims to examine stress concentration, structural deformation and contact pressure of brake
disc and pads during braking event by employing commercial finite element software, ANSYS and
CATIA for modeling purpose with considering the effect of unequal pressure application on the two
opposite side of the disc which are developed due to brake line corrosion, caliper sticking, failure of
piston seal, variation of rotor thickness and also failure of caliper bolts.
