摘要: 在磁力研磨的光整加工中,很多加工因素对其研磨效率会产生影响。针对光整加工中加工参数的选取或优化通常依赖于经验或存在反复实验的问题,该文选取平面、圆管内外表面、异形面作为研究对象,利用ANSYS Maxwell软件对主要工艺参数(例如:加工间隙、磁极形状、有无辅助磁极等)进行有限元分析。通过仿真获得了不同加工条件下的磁场状态及磁感应强度的变化规律,为加工参数选取或优化的准确性提供了分析方法和理论参考依据。Abstract: During the magnetic abrasive finishing (MAF) process, many machining factors will affect its finishing efficiency. Against the problem that selection or optimization of machining parameters always rely on experience or repeated experiments in MAF process, in this article, through selecting plane, inner and outer surface of circular tube and shaped surface as the research objects, the ANSYS Maxwell software is proposed to carry out finite element analysis on the main process parameters (such as machining gap, magnetic pole shape, auxiliary magnetic pole, etc.). The change rules in magnetic field state and magnetic induction intensity under different processing conditions are obtained through simulation. It provides an analytical method and theoretical reference for the accuracy of selection or optimization of machining parameters.
