摘要
在永磁吸附装置设计理论的基础上,提出并实现了一种变磁化方向单元组合式永磁吸附装置。该装置由若干磁化方向不同的永磁体紧密排列而成,不同磁化方向首尾相连构成环形。采用有限元法对新型永磁吸附装置进行了参数化建模、结构特性分析、磁路仿真、吸附力计算和结构参数优化。试制了相同材料和体积的新型和Halbach型永磁吸附装置,测定了单位质量吸附力与气隙厚度的关系曲线。实验结果表明,与Halbach型永磁吸附装置相比,新型永磁吸附装置的单位质量吸附力平均增加了1倍,最大增幅达2.3倍。
Based on the design theory of the permanent magnetic adsorption devices, a variable magnetization direction and unit combined device is proposed. This device is composed of closely arranged permanent magnets, whose different magnetizing directions are connected into an annulus. The finite element method is used for parameterized modeling, structural characteristic analysis, magnetic circuit simulation, adsorption force calculation, and structural parameter optimization of the proposed device. The novel and the Halbaeh type permanent magnetic adsorption devices with the same material and volume are trial-produced. The relation curves between the unit mass adsorption force and the air gap thickness are measured. The experiment results prove that the unit mass adsorption force of the novel device doubles averagely compared with the Halbaeh device, and the highest amplification is 2.3 times.
