Optimization of a Magnetic Drive Blender Orthogonal Experiment Method and Experimental Verification

Abstract

In order to solve the problems of the traditional blenders, such as short service life, easy leakage and high noise, a magnetic driven blender with disc magnetic coupler as the core stirring component was designed. The experimental design was carried out by orthogonal test method. The three-dimensional software Solidworks was used to establish the structural model of the disk magnetic coupler with nine groups of different structural parameters. The finite element software Ansys Maxwell was used to carry out numerical simulation of nine groups of different structural models of the disk magnetic coupler. The range analysis method was used to study the main and insignificant factors that affect the performance of the disc magnetic coupler, and the optimal structure parameters of the disc magnetic coupler were obtained. The results show that the level values with the most significant among all factors were the permanent magnet thickness (A3), the number of magnetic poles (B3), and the air gap spacing (C1), respectively. The optimal geometric parameter structure of the disk magnetic coupler was A3=10mm, B3=12 pairs, and C1=3mm, respectively. The performance of the optimized disk magnetic coupler was improved by 88%. It provides a design reference for the following research on the performance optimization of disc magnetic coupler.
