摘　　要：为了提高磁流变装置的力矩传递范围和稳定性,研究了具有多层动、静转子的磁流变液力矩传递装置.该装置实际上增加了剪切力的实际面积,在剪切力不变的情况下,使得输出力矩增大,在输出力矩一定的情况下,通过增加层数,使得单位面积上的载荷变小,从而保证了转子从动盘不会受力过大而发生变形甚至破坏.在深入研究磁流变液流变机理及流变特性的基础上,建立了磁流变液力矩传递装置的力矩传递模型.通过三维建模和ANSYS有限元仿真对该装置进行性能分析和结构优化设计,从而确保理论上的可行性.通过搭建的试验平台对所研制的样机进行了力矩传递性能测试.结果表明:与单层磁流变液力矩传递装置相比,该装置传递的可控力矩可成倍地增加.In order to increase the torque output range and the stability of magnetorheological fluid de vices, 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 LMTYD 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.
