基于Halbach阵列的K9玻璃磁流变抛光方法研究
Study on magnetorheological polishing method for K9 glass utilizing Halbach array
摘要
Abstract
To enhance the excitation performance and processing quality of magnetorheological polishing,a Halbach array-based permanent magnet arrangement is proposed,and the influence of process parame-ters on the polishing performance of K9 glass is investigated.Magnetic field simulations were conducted to compare the Halbach array,traditional N-S pole alternating array,and inner-outer alternating array in terms of magnetic field strength,magnetic flux density magnitude,gradient distribution,and the force act-ing on carbonyl iron particles.Combined with single-factor experiments,the effects of workpiece rotation speed,magnetic field rotation speed,working gap,and excitation gap on surface roughness and material removal rate were systematically studied.The results indicate that the Halbach array expands the effective acting area of the magnetic field,maintains good uniformity,and enhances both magnetic field strength and abrasive particle force,thereby exhibiting superior excitation performance.With increasing workpiece rotation speed,magnetic field rotation speed,and working gap,the surface roughness decreases initially and then increases,while the material removal rate increases at first and then decreases.As the excitation gap increases,the surface roughness keeps rising and the material removal rate declines.Under the condi-tions of a workpiece rotation speed of 650 r/min,magnetic field rotation speed of 70 r/min,working gap of 1.2 mm,excitation gap of 4 mm,and a polishing duration of 30 min,the surface roughness of K9 glass reaches 0.029 7 μm,and the material removal rate is 51.928 nm/min.The Halbach array excitation meth-od and its corresponding polishing process effectively improve the performance of magnetorheological pol-ishing.关键词
