摘要
介绍了磁流变液的组成和性能,阐述了磁流变液制动器的结构和原理。根据磁流变液的流变特性,推导了单盘式圆盘型磁流变液制动器和圆筒型磁流变液制动器的制动力矩公式,并在Simulink环境内建立了单盘式圆盘型磁流变液制动器和圆筒型磁流变液制动器模型,分析了2种磁流变液制动器的性能特点。分析结果可为磁流变液制动器的理论研究和设计提供参考。
The paper expounds composition and performance of Magneto-Rheological Fluids （MRF）, as well as the structure and working principle of MRF brake. Furthermore it derives braking torque formula for single disc MRF brake and drum MRF brake according to rheological property of MRF, and builds the related models in Simulink environment and then analyzes characteristics of both brakes. The analysis results can serve as a reference for the MRF research and design.
