摘　　要：分析了旋转型永磁涡流制动机的工作原理,并进行了涡流制动机机构设计。在此基础上使用有限元分析软件ANSYS建立了涡流制动机的三维模型,完成了涡流制动机的磁场分析,得出在不同的工作状态下的磁场强度分布规律。这为旋转永磁涡流制动机优化设计及控制方法的确定提供了设计依据。This paper analyzes the principle of the rotating permanent magnet eddy current brake and designs its structural mechanism.On the basis of its principle and structural mechanism,a three dimensional model of the brake is set up and an analysis of the magnetic field is done with the help of ANSYS.The analysis gives the conclusion of distribution of magnetic field in the different working-conditions.What has been done in this article also provides a design foundation for optimal designing and determining the c...
