摘　　要：为减少磁流变抛光过程中磁链屈服及磨粒沉降对材料去除效果的影响,提高磁流变抛光加工效率,基于磁流变抛光液的剪切应力模型和材料去除机理,结合工件Preston方程,建立了磁流变抛光材料去除模型;依据所建立的材料去除模型和行星式磁流变抛光加工原理,设计一种行星式磁流变抛光装置,并对抛光装置的关键参数进行计算;制作抛光装置样机并进行试验验证。结果表明,材料去除率与载液盘转速、工件转速及旋转半径呈正相关,所建立的材料去除率模型计算结果与试验结果一致性较好,所设计的装置能够达到精加工效果。In order to reduce the influence of magnetic chain yielding and abrasive setting on material removal efficiency during magnetorheological polishing,and improve the efficiency of magnetorheological polishing,a material removal model for magnetorheological polishing was established based on the shear stress model of magnetorheological polishing fluid and material removal mechanism,combined with the Preston equation of the workpiece.Based on the material removal model and the principle of magnetorheological polishing,a planetary magnetorheological polishing device is designed,and the key parameters of the polishing device are calculated.The planetary magnetorheological polishing device was produced and conduct experimental research.The results show that the rotational speed of the liquid tray,spindle speed,and rotation radius are positively correlated with the material removal rate.The calculated results of the established material removal model are consistent with the experimental results,and the designed device can achieve precision machining effect.
