摘　　要：针对现有磁流变抛光机床用回收器磁性不可调、清洗困难的问题,设计了一种基于电磁式的磁流变抛光液回收器,采用Maxwell有限元电磁仿真软件,分析了形成回收器磁性密封环端部狭缝处的磁场分布情况,验证了模型及原理的正确性和可行性,并以狭缝处磁场强度最大值为优化目标进行五因素三水平正交试验,对回收器狭缝位置和尺寸进行优化。经仿真验证,优化后的狭缝处磁场强度提高了5.2%,正交试验优化作用明显。最后,根据仿真及优化结果制作了回收器样件,并进行回收性能测试。试验结果表明:所设计的回收器能实现磁流变液的长时间稳定回收,断电后易清洗。In view of the problem that the magnetic properties of the reclaimer used in existing magnetorheological polishing machine cannot be adjusted and the reclaimer is difficult to be cleaned,a magnetorheological polishing fluid reclaimer based on electromagnetic is designed.Finite-element electromagnetic simulation software Maxwell is used to analyze the distribution of magnetic field in the end slit of the magnetic sealing ring,and the correctness and principle are verified.Taking the maximum magnetic field intensity at the slit as the optimization objective,a five-factor and three-level orthogonal experiment is designed to optimize the position and size of the slit.The simulation results show that the magnetic field intensity at the slit is increased by 5.2% after optimization,and the effect of orthogonal experiment is obvious.Finally,according to the simulation and optimization results,the sample reclaimer is processed,and the recover performance is tested.The results proved that the designed reclaimer can achieve long time stable recovery of magnetorheological polishing fluid and easy cleaning after power failure.
