摘　　要：针对电磁阀计算的手工演算程序和基于磁路方法的不足,根据工程需求情况,选择了简单、成熟的二维有限元法,提出了电磁阀的二维电磁场有限元计算模型,为利用已有的计算程序,对外施电压约束采取了迭代计算的处理方法。软件界面采用易于掌握的VB编程,计算结果的后处理则利用了Matlab的强大功能。该方法有效地解决了常用的基于磁路方法无法处理涡流场问题,并减少了设计、开发的工作量。Principle, function and design frame of a software package for electromagnetic valves are introduced. Aiming at shortages of calculation by hands and calculation by method based on magnetic circuit, finite element method(FEM) is adopted in electromagnetic field calculation. According to engineering needs, sample and mature 2D FEM is selected. Description of the 2D FEM model for electromagnetic valves is given. The problem of constraint by external voltage is solved by iteration method in order to make use of available programs. Software constitution and internal data delivery are introduced. In order to reduce the amount of work, interface of the software is developed by Visual Basic, and powerful Matlab is used in post - processing of calculating results.
