Abstract

The
concept of incorporation of fins in automobile brake drum came up as a measure
to subdue or address the thermal problems associated with it, which ultimately
leads to brake failure. In order not to compromise the original weight of brake
drum,1/10th of the overall wall thickness of the brake drum was converted into
fins on the outer surface of the brake drum for effective heat dissipation.
Modeling and simulation analysis were carried out using Solidworks (2013)
software, on both the existing and modified brake drum, followed by validation
using theoretical finite element analysis. The minimum temperatures observed
from the simulation analysis were 4935K and 4927K for the existing and the
modified brake drum model respectively. While maximum von Mises stress were and   and the maximum displacements were  and for
the existing and the modified brake drum model respectively. This implied that
the modified brake drum have improved strength and better heat dissipation rate
than the existing model.
