设计了一种新型的大功率磁流变液传动装置，并对其进行了仿真和实验研究。该传动装置由导磁柱的多个中空驱动盘组成，采用水冷方式散热。本文首先提出了一种新型导磁柱中空传动盘，并确定了大功率磁流变液传动装置的结构。然后，对磁路进行了详细设计，并用有限元方法对传动装置的磁场分布进行了分析。最后，制作了传动装置的样机，并对样机的扭矩传递、时间响应和温升进行了测试。结果表明，该磁流变传动装置的最大输出扭矩为1880N m，具有高达70kW的高滑差功率。
A novel magnetorheological (MR) fluids transmission device for high-power applications is designed, simulated and experimented. The transmission device is implemented of multi-hollow drive disc with magnetic conductive columns and adopts water cooling method to heat dissipation. In this paper, firstly, a novel hollow transmission disc with magnetic conductive columns is proposed, and the structure of the high-power MR fluid transmission device is determined. And then, the magnetic circuit is designed in detail, and the magnetic field distribution of the transmission device is analyzed by the method of finite element. Finally, a prototype of the transmission device is fabricated and several tests are carried out to evaluate the torque transmission, time response and temperature rise of the prototype. The results show that the proposed MR transmission device can produce a maximum output torque of 1880 N m and possesses a high slip power of up to 70 kW.
