Modelling and Analysis of Automotive Disc Brakes
Braking in automobiles are considered with disc brakes as the major component in the automobile that changes kinetic energy within vehicle to thermal energy and frenetic to heat dissipation and temperature rise in the disc pads and the disc brakes. Disc brakes with the help of a metallic disc along with a calliper allow the lining material within the pad, brake, across rotor to halt the vehicle. Disc brakes are employed in majority of automobiles as it retains great driveability. The high temperature and the heat dissipation can be controlled using the composite materials such as Metal Matrix Composites (MMC) and their comparison with conventional material cast iron is discussed. The major advantages of these materials are demonstrated with the enhanced strength, hardness and reduction of weight. The maximum and the minimum temperature rise of the disc rotor are also investigated with varied analysis. The mechanical behaviour of the various composition materials like Aluminium alloy, cast iron are investigated using modelling and analysis with the Space Claim modelling software and the analysis with ANSYS software with holes comparison on a simple flange type (disc rotor geometry) for effect of temperature and the heat flux is performed.
