摘　　要：针对磁流变液的流变和相变双重特性进行了研究,阐述了其流变原理。通过ANSYS有限元数值方法对力矩传递模型进行了仿真分析,在此基础上,采用SG-MRF2035型号的磁流变液,研制出了间隙为1.5mm的磁流变力矩传动装置样机,并通过搭建的测试平台对样机进行了力矩输出性能试验。试验结果表明:该装置能够输出柔顺可控力矩,为磁流变液的广泛应用开辟了一条新途径。The rheological and phase transitional dual characteristics of magnetorheological fluid were studied and its rheological principle was also described. Using ANSYS finite element method, simulation analysis of the torque transmission model was conducted. Choosing magnetorheological fluid SG-MRF2035, a magnetorheological torque servo device prototype （gap of 1. 5 mm） was developed. A performance testing platform was built to characterize the torque output of the prototype. The testing results show that the device can provide flexible output torque and the torque is continuously adjustable. This study provides a new way for the wide application of magnetorheological fluid.
