FreeCad 有限元分析入门_freecad 创建个立方体

2024.3 最新版本 0.21.2

  FreeCad 有限元分析入门

  基本步骤：

一、零件制作
        1、创建立方体
        2、修改参数
    二、建立力学分析
        1、为零件附着材料
        2、增加固定约束
        3、增加均布在表面的受力
        4、零件网格化
        5、设定保存路径，进行力学计算
        6、查看分析结果
    三、查看分析结果

修正：

 

补充：

 

创建求解器：Solver
执行求解器：Run Solver

会生成两个结果：
1、CCX_Results 
2、Pipline_CCX_Results

把Cube、FEMMeshGmsh、Pipeline_CCX_Results隐藏（选中，按空格键）
鼠标双击CCX_Results ，进入ShowResult


选择“Displacement Magnitude”

 

freecad简介

FreeCAD is an open-source parametric 3D modeler made primarily to design real-life objects of any size. Parametric modeling allows you to easily modify your design by going back into your model history and changing its parameters.

FreeCAD allows you to sketch geometry constrained 2D shapes and use them as a base to build other objects. It contains many components to adjust dimensions or extract design details from 3D models to create high quality production ready drawings.

FreeCAD is a multiplatform (Windows, Mac and Linux), highly customizable and extensible software. It reads and writes to many open file formats such as STEP, IGES, STL, SVG, DXF, OBJ, IFC, DAE and many others, making it possible to seamlessly integrate it into your workflow.

Built-in workbenches

Current

The following workbenches are bundled with every FreeCAD installation:

• Std Base. This is not really a workbench, but rather a category of 'standard' commands and tools that can be used in all workbenches.

• The Arch Workbench for working with architectural elements.

• The Draft Workbench contains 2D tools and basic 2D and 3D CAD operations.

• The FEM Workbench provides Finite Element Analysis (FEA) workflow.

• The Inspection Workbench is made to give you specific tools for examination of shapes. Still in the early stages of development.

• The Mesh Workbench for working with triangulated meshes.

• The OpenSCAD Workbench for interoperability with OpenSCAD and repairing constructive solid geometry (CSG) model history.

• The Part Workbench for working with geometric primitives and boolean operations.

• The Part Design Workbench for building Part shapes from sketches.

• The Path Workbench is used to produce G-Code instructions.

• The Points Workbench for working with point clouds.

• The Reverse Engineering Workbench is intended to provide specific tools to convert shapes/solids/meshes into parametric FreeCAD-compatible features.

• The Robot Workbench for studying robot movements. Currently unmaintained.

• The Sketcher Workbench for working with geometry-constrained sketches.

• The Spreadsheet Workbench for creating and manipulating spreadsheet data.

• The Start Workbench allows you to quickly jump to one of the most common workbenches.

• The Surface Workbench provides tools to create and modify surfaces. It is similar to the Part Builder Face from edges option.

• The TechDraw Workbench for producing technical drawings from 3D models. It is the successor of the Drawing Workbench.

• The Test Framework Workbench is for debugging FreeCAD.

• The Web Workbench provides you with a browser window instead of the 3D view within FreeCAD.
