Comparison of Drum-type and Disc-type Magnetorheological Brakes by Computational Methods
Journal Title: Gazi Üniversitesi Fen Bilimleri Dergisi Part C: Tasarım ve Teknoloji - Year 2017, Vol 5, Issue 1
Abstract
This paper presents a comparison between drum-type and disc-type magnetorheological brakes, based on torque density and efficiency. Magnetic simulations of the parametric brake designs are carried out in FEMM finite element software. The yield stress of the used commercial magnetorheological fluid is detemined based on the magnetic flux obtained from the simulations. Braking torque is analytically calculated by using the Bingham plastic model. It is shown that the brakes have similar volumes and masses at the maximum points of the comparison criteria. However the performance of the drum-type brake is found to be about twice better than the disc-type brake.
