中文摘要：

基于Bingham模型和传热学基本理论，建立滑差工况下磁流变液瞬态热传导方程，并采用数值仿真和试验研究了磁流变液温度场沿轴向和径向的分布以及滑差功率和工作间隙对其的影响规律。研究表明：轴向各间隙中磁流变液间存在着温度差异，由内向外温度逐渐降低，且内外温差随时间的增大而增加；不同时刻磁流变液表面温度分布规律基本一致，温度最高值出现在工作半径中心处；磁流变液温度随滑差时间呈近似线性上升，且温升速度随滑差功率的增大而增大，随工作间隙的增大而减小。

英文摘要：

A transient heat conduction equation under slip condition was established based on B ingham model and heat transfer theory firstly. Then, numerical simulation and experimental study were conducted to analyze the temperature distribution in both axial and radial directions as well as the effects of slip power and gap size on the temperature field. The results showed that there existed a temperature difference among the radial gaps, and the temperature gradually decreased from the inner gap to the outer gap. Moreover, the temperature difference between the radial gaps increased with the slip time. Surface temperature distribution of magneto-rheologieal fluid remained basically the same at various times. The maximum temperature appeared in the central of the working gap. The temperature of magneto-rheologieal fluid increased linearly with the slip time. Meanwhile, the temperature rise rate accelerated with the increment of the slip power, while it declined with the increase of the gap size.
