AnsysMaxwell在工程电磁场中的应用1——二维分析技术

AnsysMaxwell在⼯程电磁场中的应⽤1——⼆维分析技术学习⾃：《Ansoft12在⼯程电磁场中的应⽤》赵博、张洪亮等编著软件版本：ANSYS2019R3（1.9.7）1.1 界⾯环境左侧为⼯程管理栏，可以管理⼀个⼯程⽂件中的不同部分或管理⼏个⼯程⽂件。

其下⽅为⼯程状态栏，在对某⼀物体或属性操作时，可在此看到操作的信息。

最下⽅并排的是⼯程信息栏，该栏显⽰⼯程⽂件在操作时的⼀些详细信息，例如警告提⽰，错误提⽰，求解完成等信息。

在旁边的⼯程进度栏内主要显⽰的是求解进度，参数化计算进度等，该进度信息通常会⽤进度条表⽰完成的百分⽐。

在屏幕中部是⼯程树栏，在此可以看到模型中的各个部件及材料属性、坐标系统等关键信息，也⽅便⽤户对其进⾏分别管理。

在操作界⾯最右侧较⼤区域为⼯程绘图区，⽤户可以在此绘制所要计算的模型，也可以在此显⽰计算后的场图结果和数据曲线等信息。

如果不⼩⼼将这⼏个区域给关闭了，还可以在 View 菜单栏中将其对应项前的对号勾上，则对应的区域会重新显⽰出来。

部分快捷操作按钮如下：新建 Maxwell 3D ⼯程，新建 Maxwell 2D ⼯程，新建电路⼯程，新建 RMxprt ⼯程。

新建，打开，保存，关闭等。

复制，剪切，粘贴，撤销等。

调整视图：移动、旋转、缩放和全局视图等。

模型绘制常⽤：绘制⾯的按钮，分为矩形⾯、圆⾯、正多边形⾯和椭圆⾯；绘制线的按钮，分为线段、曲线、圆、圆弧和函数曲线。

模型材料快捷按钮。

模型校验和求解。

帮助：最好的培训教材，建议⽤户熟悉该⽂档的结构和相关内容。

1.2 Maxwell 2D 的模型绘制绘制⼆维模型时，可以采⽤快捷按钮绘图，也可以采⽤Draw下拉菜单绘制，两者的效果是相同的。

在绘制 2D 模型时 Z ⽅向上的量可以恒定为 0，仅输⼊ X 和 Y ⽅向上的坐标数据即可。

在三个⽅向上数据栏后有两个下拉菜单，第⼀个为绘制模型时的坐标，默认是采⽤ Absolut 绝对坐标，也可以通过下拉菜单将其更换为相对坐标，则后⼀个操作会认为前⼀个绘图操作的结束点为新相对坐标点起点。

Winding Bodies & Tool
• Feature: Design Modeler (DM) includes two new tools to allow a user to easily create current carrying coils: – Winding Bodies: Used to represent wound coils for source excitation. The advantage of these bodies is that they are not 3D CAD objects, and hence simplify modeling/meshing of winding structures. – Upon “attach to Simulation”, Winding Bodies are assigned as Conductor bodies. – Winding Tool: Used to create more complex coils for motor windings. The Winding Tool uses a Worksheet table format to drive the creation of multiply connected Winding Bodies. Or a user can read in a text file created by MSExcel.

IntroductionThe Magnetic Valve includes a fixed and a rotating part. The rotating body has to move, as quickly as possible, to rest in one of the 2 possible stop positions. Driving current patterns are the input to generate suitable torques.

• Feature: Design Modeler (DM) includes two new tools to allow a user to easily create current carrying coils:
– Winding Bodies: Used to represent wound coils for source excitation. The advantage of these bodies is that they are not 3D CAD objects, and hence simplify modeling/meshing of winding structures.
– Upon “attach to Simulation”, Winding Bodies are assigned as Conductor bodies.
– Winding Tool: Used to create more complex coils for motor windings. The Winding Tool uses a Worksheet table format to drive the creation of multiply connected Winding Bodies. Or a user can read in a text file created by MSExcel.

ANSYS电磁场分析例子

ANSYS电磁场分析例子我们将考虑一个简单的电磁场问题，即一个平行板电容器的电场分布。

这个问题可以很容易地通过ANSYS进行建模和求解。

首先，我们需要进行几何建模。

在ANSYS的建模界面中，我们可以使用几何建模工具来创建一个具有平行板结构的电容器。

我们可以定义平行板的尺寸、间距以及材料属性等。

接下来，我们需要定义边界条件。

在这个问题中，平行板上的电势是已知的。

我们可以在边界条件中指定平行板上的电势值，然后在求解过程中，ANSYS将根据这些边界条件计算电势分布。

然后，我们需要设置求解器选项。

ANSYS提供了多种求解器选项，包括有限元法、有限差分法等。

我们可以根据我们的具体问题选择合适的求解器。

接下来，我们需要应用材料属性。

我们可以在材料库中选择合适的材料，并将其应用于电容器的几何模型中，以便ANSYS可以根据这些材料属性计算电场分布。

最后，我们可以运行求解器并分析结果。

一旦求解器完成计算，我们可以在ANSYS的后处理界面中查看电场分布结果。

ANSYS提供了丰富的后处理工具，包括可视化和数据分析工具，可以帮助我们更好地理解和解释电场分布结果。

通过以上步骤，我们可以使用ANSYS进行电磁场分析，并得到电场分布结果。

根据这些结果，我们可以评估电容器的性能，例如电势分布、电场强度等。

这些信息对于设计和优化电容器以及解决其他电磁问题非常有价值。

总结起来，ANSYS电磁场分析是一种强大的工具，可以用于解决各种电磁问题。

通过几何建模、边界条件设置、求解器选项设置、应用材料属性和结果分析等步骤，我们可以使用ANSYS获得准确和可靠的电场分布结果，为问题的解决和优化提供有力支持。

ANSYS教程：ANSYS电磁场分析

ANSYS教程：ANSYS电磁场分析静态磁场分析：用于分析不随时间变化的磁场，主要包括三类情况：用磁场的磁场，稳恒电流产生的磁场，匀速运动的导体所产生的磁场。

对于三位静态磁场分析，ansys程序采用了两种方法：标量势法（scalar method）和单元边法（edge-based-method），其中标量势法根据其标量势方程的不同又可分为三种不同的标量势分析方法：简化标量势法（RSP）、微分标量势法（DSP）和广义标量势法（GSP）。

使用单元边法时，电流源是作为整个系统的一部分一起进行网格划分的，由此使用该方法不仅能计算常规物流量（如磁场、磁动势等），还能计算诸如焦耳热损、洛伦兹力等。

根据以下原则选择不同的分析方法：当所分析的问题中不含铁芯区域或虽含铁芯区域但不含电流源时，采用RSP法，在含有铁芯和电流源的模型分析中通常不使用RSP 法。

对于“单连通”铁芯区域模型，使用DSP法，对于“多连通”铁芯区域模型，使用GSP法。

单连通区域指的是带有空气隙的磁路不封闭的铁芯系统，没有空气隙的则为磁路封闭多连通铁芯区域系统。

对于非连续介质模型一般采用单元边法进行求解。

提示：单元边法中使用的单元的节点自由度矢量磁势是沿单元边切向积分的结果，其求解精度高于标量势法的求解精度。

单元边法不仅适用于三维静态磁场分析中，也适用于三维谐性和瞬态磁场分析中。

1 电磁场分析中的默认单位制为MKS单位制，即米、安培和秒。

可以定义其他的单位制：main menu/preprocessor/material props/electromag units2 电磁场分析中大多材料的磁性能可以从ansys程序的材料库中读入，用于也可以自己定义材料性能，方法如下：2.1 定义路径main menu/preprocessor/material props/material library/library path2.2 读入材料参数main menu/preprocessor/material props/material library/import librarymain menu/preprocessor/loads/load step opts/change mat props2.3 修正材料参数main menu/preprocessor/material props/material library/export library2.4 定义材料B-H曲线main menu/preprocessor/material props/material models/electomagnetics/BH curve2.5 在模型上施加电流密度载荷main menu/preprocessor/loads/define loads/apply/magnetic/excitation/current density/on elements2.6 施加电压载荷main menu/preprocessor/loads/define loads/apply/magnetic/excitation/volt drop/on elements2.7 进行求解main menu/solution/solve/electromagnet/static analysis/opt&solv2.8 退出求解器main menu/finish谐性磁场分析：用于分析激励源按正弦或余弦规律变化的磁场问题，如变压器、感应式电机，感应加热炉等电磁装置引发的磁场均属于谐性磁场问题。
