Design and Analysis of the Braking System to Improve Heat Dissipation by Utilizing the Multi-Material Concept

Abstract

A drum brake consists of a rotating cylinder that is pressed against by a set of shoes or pads, which creates friction. Cast iron is the typical material for this. When the brakes are applied, friction develops on the drum's inner surface, slowing or stopping the wheel's rotation and bringing the vehicle to a halt. The development of heat, especially in the braking systems of automobiles, is the primary issue that must be dealt with. Brake drums for cars are typically constructed of cast iron. Multi-material brake drums, such as those with a Nickel alloy coating over cast iron, have replaced traditional brake drums. The behavior of these two setups needs to be investigated. Brake drum modeling is being done in CREO, and ANSYS will be used for structural and thermal analysis. Stress, strain, and heat dissipation % are just few of the factors we'll be comparing. Additionally, we have conducted nickel coating experiments on cast iron using an electroplating procedure, varying the layer thickness from 10 to 15 to 25 microns.
