DESIGN ANALYSIS & OPTIMIZATION OF AN AUTOMOTIVE DISC BRAKE

Abstract

A brake is a mechanical device which simulated 
frictional safety is connected to moving machine part, to 
stop the movement of a machine. At present performing 
this function, the brakes take in either kinetic energy of the 
moving part or the potential energy surrendered by items 
being brought down by lifts and so forth. The energy 
absorbed by the brakes is scattered as heat. Disc brake is a 
recognizable car application where they are utilized broadly 
for car and bike wheels. The disc is sandwiched between 
two pads activated by cylinders backed in a caliper 
mounted on the stud shaft. At the point when the brake 
lever is pressed using pressurized hydraulic pressurized 
fluid is constrained into the chambers pushing the 
contradicting cylinders and brake pads into frictional 
contact with the disc. The frictional heat produced amid 
braking application can result in various negative impacts 
on the brake assembly, for example, brake blur, untimely 
wear, thermal splits and disc thickness variation (DTV). 
Previously, surface roughness and wear at the pad interface 
have infrequently been considered in investigations of 
thermal analysis of a disc brake finite element method. The 
main purpose of this project is to Optimization of 
Automotive Brake Disc and analysis the steady state 
thermal behavior of the dry contact between the brake disc 
and pads during the braking phase. The thermal-structural 
analysis to determine the deformation and the Von Misses 
stresses established in the disc. The objective of the project 
is the design, analysis and optimization of solid and 
ventilated disc brake using Solid works, Hyper mesh and 
Ansys. The ventilated brake disc assembly is built by a 3D 
model in Solid Works and imported to ANSYS to evaluate 
the stress fields and of deformations which are established 
in the disc with the pressure on the pads and in the 
conditions of tightening of the disc.
