Ansys Workbench 电磁阀磁场分析

本人最近由于在做电控燃油系统，正好牵扯到电磁铁的计算，看到好像没人发过，于是就自己发一个，参考了AWB帮助的例题，有什么不正之处还请大家指教首先在proe里建模，绿色是电磁铁，黄色是衔铁，两者间隙0.28mm。

然后直接进入DM建立线圈和周围的空气。

在DM中新建一个plane，为的是建立线圈。

这个plane是基于图中绿色平面沿Z轴负向的一个距离-5.5mm
在新建的plane上新建草绘，然后画一个直径16.5的圆，这个圆是线圈中心尺寸
下一步从这个圆生成线体，如下图，选择草绘的圆
然后选择生成的线体，在winding body？中选择yes
设置线圈的圈数为71,高度为9mm,宽度为1mm，然后选view--cross section solid，隐藏衔铁和电磁铁可以看到线圈
建立包围的空气
形状选圆形，在merge parts?中选y es
保存DM文件，进入simulation，选择衔铁和电磁铁的材料为纯铁
网格划分在这里就不讲了，画完网格后，在new analy sis中选magnetostatic
然后选择conductor winding body，输入线圈中的电流值为12000mA
插入磁通平行条件，在磁通平行的scoping method 选name selection,在name selection中选open domain
在solve中插入磁感应强度和衔铁所受的磁力，在directional force/torque 的geometry中选择衔铁，方向选择Z轴
最后右键进行solve，由于材料B-H曲线是非线性的，因此计算时间有点长。
