采用ANSYS磁场求解方法,建立动静磁环3D有限元模型,并得出动磁环位移特性的力学分析。结合动静磁环的结构中静磁环内径的包络区域,文章给出了动静磁环组成磁环对的位置特性,这对于永磁环构建永磁轴承的设计具有指导性建议。
The 3D finite element model of dynamic and static magnetic rings is build by the solving method of magnetic field,and the mechanical analysis of displacement characteristic of dynamic ring is then acquired.According to the insider diameter envelop region of static magnetic ring,the position characteristic of magnetic bearings couple constructed by magnetic rings is described,which is a guiding suggestion for design of permanent magnetic bearing constructed by magnetic rings.
