Research on Magneto-Rheological Torque Servo Devices

Abstract

The dual characteristic of magnetorheological rheology and phase transitions is studied and its rheological principle is also described. By using the ANSYS finite element method, a simulation analysis of the torque transmission model is conducted. By selecting the magnetorheological fluid SG-MRF2035, a magneto-rheological torque servo device prototype (Gap of 1.5mm) is developed. And a performance testing platform is built for the torque output characteristics of prototype. The test results show that the device could provide supple output torque and the torque is continuously adjustable. This paper provides a new way for the wide application of magnetorheological fluids.
