description |
One of the benefits of electric vehicles (EVs) and hybrid vehicles (HVs) is
their potential to recuperate braking energy. Regenerative braking (RB) will
minimize duty levels on the brakes, giving advantages including extended
brake rotor and friction material life and, more significantly, reduced brake
mass and minimised brake pad wear. In this thesis, a mathematical analysis
(MATLAB) has been used to analyse the accessibility of regenerative braking
energy during a single-stop braking event. The results have indicated that a
friction brake could be downsized while maintaining the same functional
requirements of the vehicle braking in the standard brakes, including
thermomechanical performance (heat transfer coefficient estimation,
temperature distribution, cooling and stress deformation). This would allow
lighter brakes to be designed and fitted with confidence in a normal
passenger car alongside a hybrid electric drive. An approach has been
established and a lightweight brake disc design analysed FEA and
experimentally verified is presented in this research. Thermal performance
was a key factor which was studied using the 3D model in FEA simulations.
Ultimately, a design approach for lightweight brake discs suitable for use in
any car-sized hybrid vehicle has been developed and tested. The results
from experiments on a prototype lightweight brake disc were shown to
illustrate the effects of RBS/friction combination in terms of weight reduction.
The design requirement, including reducing the thickness, would affect the
temperature distribution and increase stress at the critical area. Based on the
relationship obtained between rotor weight, thickness and each performance
requirement, criteria have been established for designing lightweight brake
discs in a vehicle with regenerative braking. === Ministry of Higher Education of Malaysia |
