MRF is one kind of intelligent liquid with outstanding performance. After Appling a magnetic field, it can transform thin liquid to thick liquid, and this transformation is quick, controllable and reversible, fluid. This excellent characteristic vehicles enables its application in, such as brakes, clutch, suspension, etc.
This thesis discussed the anti-lock braking system (ABS) to understand the relationship between braking stability and slip ratio. A novel patented magneto-rheological fluid brake, which was invented by our laboratory, was used to provide fast braking response. The fuzzy logic theory was applied to design an intelligent controller for the ABS system. The entire system was simulated by BikeSim to analyze the motorcycle dynamics under different road conditions. The simulated performances for MRF ABS system and conventional hydraulic ABS system were compared. The results showed that the MRF ABS system significantly improved the slipping during brake, and shortened the braking distance. Finally, a MRF brake was manufactured and assembled to be installed in a MRF brake testbed for verification test. The output torque of the MRF brake was tested for different rotational speeds and currents.
