Abstract:In order to increase the torque output range and the stability of magnetorheological fluid devices, a layered magnetorheological torque transmission device was investigated. Due to the device, the area of shearing force was increased, and the output torque was increased when the shearing force was constant. In the case of a constant output torque, the load per unit area was decreased by adding the number of layers to ensure driven disk rotor not distorted and broke by excessive force. The rheological mechanism and the performance of magnetorheological fluids were investigated to establish LMTTD torque transmission model and perform related mathematical model. By ANSYS finite element method, the LMTTD simulation analysis and structural optimization design were conducted to ensure the feasibility of theory. A performance testing platform was built to realize the torque output performance experiment. The result shows that compared with unlayered devices, the proposed device can increase output torque exponentially.
