摘　　要：多倍捻锭子利用磁场作用力传递转矩,它的结构参数、永磁体分布影响磁力的大小变化,因此需要进行轴向磁力计算。针对轴向磁力传动结构,由经验求解法和等效磁荷原理建立磁力计算数学模型,采用有限元分析软件,通过仿真与计算,探讨磁力线、磁感应强度和磁场强度分布,研究不同计算方法时的磁转矩值,为轴向磁力传动结构优化设计和磁路分布提供依据,具有重要的实际应用价值。The torque of multi-twisting spindle is transmitted by magnetic field.Calculation of axial magnetic force is necessary because of magnetic force varied with the spindle＇s structure parameters and permanent magnet distribution.The mathematic model is constructed with the experience solution and the principle of equivalent magnetic charge in view of the structure of axial magnetic transmitting.The ANSYS software is adopted for simulation and calculation of magnetic force to get the distribution of magnetic force line,magnetic field intensity and magnetic flux intensity.These analysis benefit from the optimize design of axial magnetic transmitting machine and the permanent magnet distributing and is important practical applications.
