摘　　要：为了克服磁流变液制动器因制备液沉淀而造成其制动性能下降或失效的问题,提出了一种新型环流式磁流变液制动器,分析了其制动性能与外加磁场强度之间的关系,并用ANSYS进行了磁路分析,证明其制动性能符合国家标准,从而为磁流变液制动器的设计与研究提供了可靠的参照。To overcome the decrease in braking performance of the magnetorheological fluid brake due to the precipitation of magnetorheological fluid, the paper designed a new type of circumfluent magnetorheological fluid brake, and analyzed the relationship between the braking performance and the external magnetic field strength. In addition, it analyzed the magnetic circuit by ANSYS, and the analysis results showed that its braking performance met the requirements of national standards. The study offered reliable reference for the design and research of the magnetorheological fluid brake.
