摘　　要：针对机床用磁悬浮直线进给单元设计过程中的磁悬浮支承问题,比较了两种磁悬浮工作原理,确定了单自由度吸力型磁悬浮支承模型,并推广到五自由度磁悬浮直线进给单元模型的建立。运用SolidWorks三维软件设计了两种磁悬浮直线进给单元支承立柱,并运用ANSYS有限元软件对其进行定位分析,计算出了两种平台的支承立柱在进给方向和导向方向的最佳位置。所做的计算与分析可用于机床用磁悬浮直线进给单元结构的优化设计。The comparison of two kinds of magnetic suspension principle is presented by aimed at the problem in application of maglev supporting technology used for the design of maglev linear feed unit.Referring to the built single degree of freedom magnetic levitation bearing model,the model of maglev linear feed unit with five degrees of freedom （5-DOF）was established.Two kinds of supporting pillar of maglev linear feed were designed by using the Solidworks 3-D software.After their positioning analysis carried out with the help of the finite element software ANSYS （FEA）,the best supporting position of pillars for two kinds of platform respectively in the linear feed direction and the guide direction were calculated.The calculation and analysis presented can be used to design with optimization the structure of the maglev linear feed unit.
