Paper Abstract

Magnetorheological brakes (MRBs) have the characteristics of simple structure, fast response and large controllable range, which would effectively improve the vehicular braking efficiency and stability. They have been utilized in the intellectualization and electrification of vehicles. A brake-by-wire actuator namely MRB, is designed, optimized, manufactured in this paper. It is composed of an input shaft, brake discs, fixed discs, an excitation coil, and shells. A hardware-in-the-loop test bench is established and the anti-lock braking system (ABS) experiment is conducted. Specifically, the braking torque of MRB is matched to a minicar and a multi-disc MRB is designed. In order to improve the mechanical properties and lightweight design of MRB, the magnetic circuit design and multi-objective structural optimization are carried out by ANSYS/ADPL programming. The prototype development and calibration of MRB mechanical properties are conducted according to the optimized parameters. The test bench of the braking system is established, and the single-wheel ABS tests for the MRB is implemented and evaluated.
