Design and Thermal Analysis of Disc Brake for Sports Bikes

Abstract

At the IAA in Frankfurt in 1999, the carbon-ceramic brake disk had its world premiere. The use of the high-tech material had revolutionized the brake technology: In comparison to the conventional grey cast iron brake disk the carbon-ceramic brake disk weighed round 50 per cent less reducing the unsprang mass by almost 20 kilograms. Further significant advantages are: improved brake response and fading data, high thermal stableness, no hot judder, excellent pedal feel, improved steering behavior, high abrasion resistance and thus longer life time and the advantage of avoiding almost completely brake dust. At first Porsche AG built the carbon-ceramic brake disk in 2001 into the 911 GT2 as series equipment. Since that time also other premium brands use the advantages of this innovative brake technology for more security and comfort. These are for example sports cars and luxury class limousines from Audi, Bentley, Bugatti and Lamborghini.

In this paper we will design a disk break using carbon ceramic composite for high speed two wheelers. The main aim of this paper is to design a composite disk break with least possible production cost and long life, for achieving this goal we will compare different models of structural models of disk brakes with different materials finally we conclude the best model and material based on the thermal behavior and stress concentrations of each model, for designing disk brakes we use Catia V5 R21, and for analysis we use Ansys 14.5
