RESEARCH ON REGENERATIVE BRAKE DESIGN USING MAGNETORHEOLOGICAL FLUID

Abstract

Regenerative braking is an advanced braking system that is used in
conjunction with traditional braking systems, converting the kinetic energy of
the braking process into electricity for reuse. With the research and design of
regenerative brakes using magnetorheological fluid (MRF), the rotor shaft of
the generator will be driven through the active shaft thanks to the power
transmission properties of MRF during operation. When not in operation, the
brake mechanism is not supplied with current, the oil layer is in a liquid state,
the active shaft is not linked to the fixed shaft. When braking, the system will
supply an electric current, and the MR fluid layer changes to a solid state to
drive from the active shaft, linked to the fixed shaft, rotating the generator
rotor. With the application of the regenerative braking using
magnetorheological fluid, it is possible to optimize the power source on rear-
wheel drive passenger cars. In this research, a new shape of regenerative brakes
using magnetorheological fluid is designed. Using magnetic field simulation
and analyzing calculated data to evaluate the efficiency of the field current and
the generated voltage.
