Ansys教程：自下向上实体建模建立连杆模型

练习目的：熟悉从下向上建模的过程

1. 进入ANSYS工作目录,将 “c-rod” 作为jobname。
2. 创建两个圆面：
– Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > By Dimensions ...
? RAD1 = 1.4
? RAD2 = 1
? THETA1 = 0
? THETA2 = 180, 单击[Apply]
? 然后设置THETA1 = 45,再单击[OK]
3. 打开面:编号
– Utility Menu > PlotCtrls > Numbering ...
? 设置面号on, 然后单击[OK]
4. 创建两个矩形面:
– Main Menu > Preprocessor > -Modeling- Create > -Areas- Rectangle > By Dimensions ...
? X1 = -0.3, X2 = 0.3, Y1 = 1.2, Y2 = 1.8, 单击[Apply]
? X1 = -1.8, X2 = -1.2, Y1 = 0, Y2 = 0.3, 单击 [OK]
5. 偏移工作平面到给定位置 (X=6.5):
– Utility Menu > WorkPlane > Offset WP to > XYZ Locations +
? 在ANSYS输入窗口输入6.5
? [OK]
6. 将激活的坐标系设置为工作平面坐标系:
– Utility Menu > WorkPlane > Change Active CS to > Working Plane

7. 创建另两个圆面:
– Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > By Dimensions ...
? RAD1 = 0.7
? RAD2 = 0.4
? THETA1 = 0
? THETA2 = 180, 然后单击[Apply]
? 第二个圆THETA2 = 135, 然后单击[OK]
8. 对面组分别执行布尔运算:
– Main Menu > Preprocessor > -Modeling- Operate > -Booleans- Overlap > Areas +
? 首先选择左侧面组, 单击 [Apply]
? 然后选择右侧面组, 单击[OK]
9. 将激活的坐标系设置为总体笛卡尔坐标系:
– Utility Menu > WorkPlane > Change Active CS to > Global Cartesian
10. 定义四个新的关键点:
– Main Menu > Preprocessor > -Modeling- Create > Keypoints > In Active CS …
? 第一个关键点, X=2.5, Y=0.5, 单击[Apply]
? 第二个关键点, X=3.25, Y=0.4, 单击[Apply]
? 第三个关键点, X=4, Y=0.33, 单击[Apply]
? 第四个关键点, X=4.75, Y=0.28, 单击[OK]
11. 将激活的坐标系设置为总体柱坐标系:
– Utility Menu > WorkPlane > Change Active CS to > Global Cylindrical
