Performance Analysis of Various Disc Brake Profiles

Abstract

A Disc brake is a device that retards/halts the rotation of a shaft / wheel. A disc brake system consists of a brake disc, a brake caliper and brake pads. When the brake pedal is applied, pressurized hydraulic fluid squeezes the brake pad friction material against the surface of the rotating brake disc. The result of this contact produces friction which enables the vehicle to slow down or stop. Due to this friction, heat will be generated and the brake disc gets heated up which affects the performance of the disc brake under different braking conditions. In this paper focus is primarily emphasized on the comparative performance of disc brakes having different profiles, by determining the heat generated and von-misses stress developed in the brake disc for different braking conditions using ANSYS 14.5.
