在研究圆筒式径向磁力驱动器结构特点、设计流程、设计方法的基础上,以SolidWorks为软件支撑平台,利用Visual Basic语言对SolidWorks提供的API函数进行二次开发,所形成的仿真系统包括3部分,分别为参数化设计、参数化建模和参数化有限元分析,可以快速地实现磁力驱动器各部分零件的自动建模和装配.同时,基于ANSYS有限元软件,对圆筒式径向磁力驱动器的磁场建立二维模型,对其磁场进行数值求解计算,分析磁力线分布,磁感应强度分布和磁力矩大小.最后,针对有限元软件在磁力驱动器设计中的应用要求,基于ANSYS平台开发了参数化的磁力驱动器有限元分析系统,该系统方便了磁力驱动器在一定结构不同参数下快速更新模型和进行有限元仿真分析,为磁力驱动器的研究提供了高质量低成本的设计分析方法.

Based on the analysis of characteristics of the structure,design flow and design method of the cylinder typed radial magnetic driver,the secondary development of the API function of SolidWorks was carried out by applying Visual Basic language on the supporting platform of SolidWorks software.The magnetic driver simulation system contains three parts,such as parametric design,parametric modeling and parametric finite element,and it could realize the auto-modeling and assembling of every parts of the magnetic drive quikly.Based on ANSYS software,the study use vector potential method and scalar potential method to build 2D models of the magnetic field of cylinder typed radial magnetic driver,then do the solution computation and analysis the distribution of magnetic line,the distribution of magnetic induction and the size of the moment of magnetic force.A template for magnetic drivers structure calculating and analysis based on ANSYS is built.The developed magnetic driver simulation system,under different design parameters,is advantageous for the magnetic driver to rebuild the model fast,and carry on the finite element simulation analysis,that explored a lower consumption higher quality design and analysis method.
