中文摘要：

设计了多盘式磁流变液离合器的结构，其能传递较大功率。基于热传导理论，采用有限元方法对多盘式磁流变液离合器内部温度场进行了研究。结果表明，滑差功率较小时，磁流变液离合器整体温度分布较为均匀。温度最低点出现在轴端，最高点出现在传动圆盘内外径之间，此时该装置能够长时间运行；滑差功率较大时，磁流变液内部温度随时间增加呈上升趋势。

英文摘要：

This paper designs a multi-disk magnetorheological fluid （MR fluid） clutch, which can pass a larger power. Furthermore, based on heat conduction theory, the temperature field of Muhidisc- Shaped MR fluid Clutch is studied using finite element method. The result indicates that ：when slip power is small, the temperature distribution of multi-disk MR fluid clutch is uniform. The lowest temperature appears at the end of the shaft and the highest point appears between the drive discs. At this time, the Multidisc-temperature of MR fluid Shaped MR fluid Clutch can run a long time. When slip power is higher, the increases with the time.
