摘　　要：磁场形成部件是磁性磨粒光整加工设备的核心部件,用于在加工区域中产生特定大小的磁感应强度,磁化磁性磨粒而形成作用力,加工区域的磁感应强度大小直接影响到工件的加工效果与加工效率。基于电磁源与永磁源分析,及电控永磁起重机与电控永磁夹具原理设计了电控永磁磁场形成部件。理论分析计算空气隙的磁感应强度,其磁感应强度大小可通过线圈电流大小控制,加工范围广,能耗低,并通过ANSYS仿真分析对结果进行了验证。设计了另外几种电控永磁磁路与原方案进行结构对比优化,分析了各种方案的优缺点及其适合的加工场合。Magnetic formation components is the key part in magnetic abrasive finishing, which is used to produce a specifw magnetic induction intensity in processing region, and magnetize magnetic abrasive to form the acting force. Magnetic induction strength directly affects the processing effect and processing efficiency of the workpiece. The electronically controlled permanent magnetic field forming part is designed based on the analysis of electromagnetic source and permanent source, and the principle of electronically controls permanent cranes and the electronically controls permanent fixture. The magnetic induction intensity of air gap is calculated through theoretical analysis, which can be controlled through the coil current, and it＇s processing range is wide, energy consumption is low. The results are verified through ANSYS simulation analysis. Several other magnetic circuit of electric control permanent magnetic field formed member is designed to compare with the original program structure, and analyze the advantages and disadvantages of the various programs and the occasions of appropriate processing.
