文章以磁力搅拌釜中的磁力联轴器为研究对象,建立有限元模型并对最大静磁转矩进行分析。针对磁力联轴器的结构特点,研发了基于Ansoft Maxwell和Python混合编程的磁力联轴器磁转矩仿真计算的可视化软件。软件通过读取必要的参数,能自动完成磁力联轴器的参数化建模与磁转矩的仿真分析,提高了计算效率。同时为做到经济性与轻量化设计,采用Ansys Workbench中的响应面优化模块以永磁体体积最小为目标进行多参数优化,构建了关于永磁体体积的响应面模型,并耦合MOGA遗传算法得到了最佳的设计参数。

Taking the magnetic coupling in a magnetic stirring reactor as an object,finite element models were established to analyze the maximum static magnetic torque.Based on the structural characteristics of the magnetic coupling,the visualized software for the magnetic torque simulation and calculation of magnetic couplings was developed with Ansoft Maxwell and Python.By reading the necessary parameters,the software can automatically complete modeling of the magnetic coupling and performing simulation analysis of the magnetic torque,which obviously improve the calculation efficiency.In addition,for a economy and lightweight design,the response surface optimization module in Ansys Workbench was used to optimize multiple parameters for minimizing the volume of permanent magnets.As a result,a response surface model about the volume of permanent magnets was constructed,and the MOGA genetic algorithm was coupled to obtain the optimal design parameters.
