Abstract: The aim of this work is to understand the performance variations of magneto-rheological brake system by considering the different shapes of brake envelopes. The shapes selected for brake envelopes are rectangular, dumbbell, shell type and 7-segment and find out the most suitable shape or geometry. MR brakes of different shapes were modelled and the braking torque for each envelope was found out. By using ANSYS Mechanical APDL optimization of MR brakes with different shapes is performed. From the results most suitable MR brake system were identified and discussed.
