磁流变液是磁流变传动装置的工作介质，传动装置的力矩传递是靠磁流变液的屈服剪切应力实现的。基于流体动量方程和Bingham模型原理，对磁流变传动装置的动态特性进行了数值计算与分析。试验结果表明，可以通过调节磁电流来控制传动装置的转矩，与理论分析结果基本符合；试验装置输出的转矩具有良好的恒转矩特性，且有很灵敏的动态响应特性。通过数学建模与仿真分析，为磁流变传动装置提供了可靠性设计与特性分析的依据。

MRF as working medium of MRF actuator,the torque of gear transmission relies on the yield shear stress of MRF fluid,in the paper,based on the principle of momentum equation of fluid and Bingham model,the dynamic character-istics of MRF actuator has carried on the numerical calculation and analysis,the experimental results showed that it can be controlled by adj usting the magnetic current transmission torque,and results are basically in agreement with theoretical a-nalysis.Experimental apparatus of the output torque has good constant torque characteristics,dynamic response is very sen-sitive.In the paper,through mathematical modeling and simulation analysis for MRF actuator provided the basis of reliabili-ty design and characteristics analysis.
