Abstract :

Disk brakes have been used for many years in automobiles and are still undergoing further development in terms of the temperatures that they can reach and operate safely at. Many new materials have been introduced for the disk brake rotor to withstand high temperature produced during braking action. Apart from the high temperature property, the disc rotor materials must also have high thermal conductivity property, as this property decides the amount of heat dissipation to the air stream from the disk rotor. A brake material with good temperature and high thermal conductivity property gives maximum efficiency by overcoming the problem of thermomechanical instability [TEI] in the rotor which is more common in low thermal conductivity brake rotor material. In the present work, a Grey cast iron and metal-ceramic material has been chosen for the disk brake rotor. Many methods have been introduced in the past to simulate and predict the temperature history of the different disk brake materials, To simulate and predict the temperature history for the Grey cast iron material, and metal-ceramic, a numerical simulation is carried out in ANSYS to predict temperature distribution as a function of time in the disk brake rotor. The results from the transient analysis are compared. From the analysis, the best material for the brake Rotor metal-ceramic as far as thermal and structural behavior is concerned in order to prevent “thermal elastic instability”.
