Designing, Manufacturing and Testing the Cycling Training System Featuring Magnetorheological Brake

摘要

In this study, a dual-disc magneto-rheological brake (MRB) with two coils placed on each side housing is proposed for a cycling training system. The cycling training system is integrated a positioning system to simulate the cycling process in different slope ranging from 0 to 15°. By adjusting position of the bicycle, braking torque of the brake, a cyclist can experience different riding condition such as riding on flat road or steep road with the slope up to 15°. After an introduction of configuration of the cycling training system, the configuration of dual-disc brake with two coils placed on each side housing is proposed and its braking torque is derived base on Bingham plastic model of MR fluid. The proposed brake are then optimally designed and simulated. The optimized MRB is then manufactured and it performance characteristics are then experimentally investigated. In addition, a positioning system actuated by a servo motor is designed to simulate the slope of road. A control system is then designed for the cycling training system and performance of the cycling training system is then experimentally validated.
