Study on A Disk - Shaped Magnetorheological Actuator

This paper studies the design of a disk - shaped magnetorheological actuator' s main structural parameters. It involves with the dynamic characteristics of the actuator, the physical properties of the MRF as well as the operating conditions of the actuator. Transmitted torque, dynamic quality, range of speed regulation, viscous power loss, stiffness of the actuator, as well as speed difference- magnetic intensity coefficient of are discussed in this paper. All of these are related to inner & outer diameters of the disc, clearance height, shear rate, applied magnetic intensity, off state viscosity and yield stress.
