Elaborate on the braking system performance relation with braking frequency. Use graphs.
Brakes are basically devices used in the conversion of kinetic energy to thermal energy. Automobiles generally use the friction type of braking system which consists of a group of mechanical, hydraulic and electronic activated components. The automobile friction type braking system is either the disc or the drum system.
The impact of the vehicle speed and duration of braking have
been undertaken, and it has been reported that it is imperative
that the heat generated must be adequately dissipated to ensure the
proper functioning of the system. The relatively low temperature at
which materials could fade has been a major reason for
consideration in the choice of materials for disc braking systems,
because of the very high temperature which is obtainable during
braking. Fading is one of the reasons why aluminum, despite being a
good thermal conductor and lightweight is not used in its pure form
for disc braking system because of its low operating
temperature.Figure 2 gives the idea about the temperature
varaiation with rescpect to time.
