摘　　要：提出一种由形状记忆合金(Shape Memory Alloy,SMA)驱动通过改变磁流变液的工作面积来改变传递转矩的传动方法;介绍了其工作原理,分析了变面积的过程;基于磁路理论,进行传动装置的磁路计算;应用ANSYS软件进行了磁路建模和有限元仿真,得到不同面积比下的磁感应强度分布云图;最后对比分析了不同面积比下传递转矩的能力。结果表明:随着磁流变液的面积比增大,传递的转矩先增大后减小,传动能力得到提升。A transmission method for changing the transmission torque by changing the working area of the magnetorheological fluid driven by shape memory alloy was proposed.Its working principle was introduced and the process of variable area was analyzed.Based on the theory of magnetic circuit,the magnetic circuit of transmission device was calculated.The magnetic circuit modeling and finite element simulation were carried out with ANSYS software,and the magnetic induction intensity distribution cloud map with different area ratios was obtained.Finally,the ability to transmit torque under different area ratios was compared and analyzed.The results show that as the area ratio of magnetorheological fluid increases,the transfer torque first increases and then decreases,and the transmission capacity is improved.
