| Summary: | The prediction of surface temperature for brake rotor is
regarded as an important step in studying the brake
system performance. The frictional heat generated on
the rotor surface can influence excessive temperature
rise which in turn leads to undesirable effects such as
thermal elastic instability (TEI), premature wear, brake
fluid vaporization (BFV) and thermally excited
vibrations (TEV). The purpose of this study is to
investigate the temperature distribution profile for
brake caliper pressure application of 0.5, 0.10, 1.5 and
2.0 MPa with a speed of 60km/h braking condition on
the disc rotor surface. The brake rotor assembly is built
by using a 3 dimensional finite element model of a real
car brake rotor. To verify the simulation results, an
experimental investigation is carried out. It is believed
from the study that composite brake rotor influences
the temperature distribution and heat dissipation rate
which could prevent excessive temperature rise and
subsequently prolong the service life of the rotor. The
finite element method is cost effective and also assists
the automotive industry in producing optimised an |
