摘　　要：为了更好地研究磁流变液的宏观性能和温度对屈服应力测试装置的影响,首先从微观角度来分析磁流变液的链化过程,通过数值模拟与实验观测相结合的方式来分析磁流变液内部链化形成结构。然后利用Fluent仿真软件模拟屈服应力测试装置的温度场,通过仿真云图来探究其温度对屈服应力测试装置的影响。最后对屈服应力测试装置进行优化与改进,来更好地提高磁流变液测试装置的精确度,也为磁流变液的制备配方和设计提供了参考依据。In order to better study the macroscopic properties of MRF and the influence of temperature on yield stress testing device,this paper firstly analyzed the chain formation process of MRF from a micro perspective,and analyzed the internal chain formation structure of MRF by combining numerical simulation with experimental observation.Then the temperature field of the yield stress testing device was simulated by Fluent simulation software,and the influence of its temperature on the yield stress testing device was explored by simulation cloud chart.Finally,the yield stress testing device was optimized and improved to improve the accuracy of MRF testing device,and laid a foundation for the preparation formula and design of MRF.
