Abstract: The braking performance of MRB(magneto-rheological brake)based on braking controller was mainly explored in this paper. The main research contents included design and structural optimization to obtain the optimum MRB. In order to study its braking performance,the MRB controller was designed based on the Arduino board and the L9349 power driver IC. Deceleration experiment and braking torque following experiment with different step signals and sine signal were carried out for exploring braking performance. The results indicate that the MRB′s response time is about 40ms,the delay time is about 70ms,and the lag braking time is about 20ms in the following process that was faster than that of the hydraulic braking system. This study may has great significance with laying a foundation for the development and application of MRB.
