Abstract

A transmission method of magnetorheological(MR) fluid in disc type driven by shape memory alloy (SMA) spring with the thermal effect was proposed. The torque changed at difference temperatures. Based on the thermal effect of SMA, the expression for displacement of SMA spring was established and the rheological properties of MR fluids under the magnetic fields was described by Herschel-Bulkley model. The shear flow of MR fluid between two discs was analyzed by the momentum equation and the expressions of flow velocity and torque were obtained. The experimental results show the displacement of SMA spring and the transmit torque of MR Fluid are directly proportional to the temperature and the applied magnetic field, respectively. The transmit torque of MR Fluid can be continuously controlled by the SMA spring in difference temperatures.
