Notice of Retraction Disc shaped high-torque-MRF-clutch design

A disc shaped Magnetorheological Fluid (MRF) clutch with low idle and high transmittable torque and good long term stability designed and characterized. The torque-transmit ability equations of disc shaped clutch were derived. The problem of particle centrifuging was discussed, and a nondimensional parameter was also put out which clearly specifies the influence of different variables on the stability against demixing of MRF. Experimental results of the designed clutch concerning transmitted torque are presented. It was demonstrated that the clutch is capable of producing high controllable torques.
