Abstract
A magnetorheological (MR) fluid brake is a device that transmits torque by the shear force of an MR fluid. An MR rotary disk brake has the property that its braking torque changes quickly in response to an external magnetic field strength. This paper presents theoretical considerations of the design alternative for usual simple MR fluid brake. The equation of the torque transmitted by the MR fluid within the brake is derived to provide the theoretical foundation in the cylindrical design of the brake. Based on this equation, after mathematical manipulation, the calculations of the volume, thickness and width of the annular MR fluid within the cylindrical MR fluids brake are yielded.
