摘　　要：针对大口径光学零件抛光过程中存在抛光效率低、面型精度不高等问题,基于大面积接触思路,采用电磁铁产生梯度磁场的方式,提出了一种“缎带”状磁场发生结构,介绍了圆柱形磁流变抛光头组成模块,利用有限元仿真软件对磁场进行了模拟优化,分析了左右磁极宽度、气隙宽度和磁芯宽度等主要因素对磁场的影响规律,并进行了工艺试验。结果表明:圆柱形磁流变抛光头可以实现光学零件的表面高质量抛光,设备结构简单,具有一定的实用价值。Aiming at the problems of low polishing efficiency and low surface accuracy in the polishing process of large-diameter optical parts,based on the concept of large-area contact,a"ribbon"shaped magnetic field generation structure is proposed by using an electromagnet to generate a gradient magnetic field.The composition module of the cylindrical magnetorheological polishing head is introduced,and the magnetic field is simulated and optimized by using finite element simulation software.The left and right magnetic pole widths are analyzed.The influence of main factors such as air gap width and magnetic core width on the magnetic field was studied,and process experiments were conducted.The results show that the cylindrical magnetorheological polishing head can achieve high-quality polishing of optical components on the surface,with a simple equipment structure and certain practical value.
