MODELING AND ANALYSIS OF DISC BRAKE PERFORMANCE

In automotive industry, disc brake is a device that plays a vital role in
slowing or stopping the rotation of a wheel. Abrake disc, which is usually made of
cast iron or ceramic, is connected to the wheel or the axle. To stop the wheel,
friction material in the form of brake pads (mounted in a device called a brake
caliper) is forced mechanically, hydraulically, pneumatically or electromagnetically
against both side of the disc. Friction causes the disc and the attached wheel to
decelerate or stop. Current disc brakehas weaknesses either from the designandthe
application, which causes the damages to the brake. This research attempts to
investigate a ventilated disc brake with the aim to improve the stopping time,
material used for disc caliper and brake pad and the optimization of the brake disc
position.
The project will employ the method of simulation in ANSYS software,
which is a software used to analyze the air flow and dynamic inside the brake rotor
vane, as well as thermal stress analysis of ventilated brake disc. The data are
gathered from trusted resources such as from internet, books, journal and
dissertation thesis to be used in the simulation. The result from the simulation using
the detail in Proton Waja's disc brake will be a reference to improvethe design.
This research aims mainly to find an optimum braking performance and to
reduce the percentage of damage modes reoccurrence. If the braking time and
damage modes are reduced using the best material chosen, then this project has
succeeded to achieve its goal.
