【Abstract】 Working principle and design criteria for magneto-rheological transmission device(MRTD) were analyzed based on Bingham viscoplastic model.A prototype of MRTD was designed and manufactured,some experiments about it had been done.The experimental results reveal that the transfer torque of MRTD can be controlled by adjusting the exciting current.The testing data for transfer torque of MRTD are coincident with the theoretical ones.MRTD has a good constant-torque performance and its transfer torque almost maintains a constant value with variation of slipping speed.MRTD also has a fast dynamic response characteristic.The analysis method presented is reasonable,which provide key guidance for reliable design and efficient control of MRTD.更多还原
