,用“c-rod”作为作业名,进入ANSYS.
2. 创建两个圆形面:
–Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > By Dimensions ...
•输入RAD1 =
•输入RAD2 = 1
•输入THETA1 = 0
•输入THETA2 = 180, 然后选择[Apply]
•输入THETA1 = 45, 然后选择[OK]
–或用命令:
/PREP7
PCIRC,,1,0,180
PCIRC,,1,45,180
3. 打开面号:
–Utility Menu > PlotCtrls > Numbering ...
•设置面号为“on”, 然后选择[OK]
–或用命令:
/PNUM,AREA,1
APLOT
4. 创建两个矩形面:
–Main Menu > Preprocessor > -Modeling- Create > -Areas- Rectangle > By Dimensions ...
•输入X1 = -, X2 = , Y1 = , Y2 = , 然后选择[Apply]
•输入X1 = -, X2 = -, Y1 = 0, Y2 = , 然后选择[OK]
–或用命令:
RECTNG,-,,,
RECTNG,-,-,0,
5. 平移工作面位置(X=):
–Utility Menu > WorkPlane > Offset WP to > XYZ Locations +
•回车后在输入窗口输入 , [OK]
–或用命令:
WPAVE,
6. 设置工作平面所在的坐标系为激活坐标系:
–Utility Menu > WorkPlane > Change Active CS to > Working Plane
–或用命令:
CSYS,4
:
–Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > By Dimensions ...
•输入RAD1 =
•输入RAD2 =
•输入THETA1 = 0
•输入THETA2 = 180, 然后选择[Apply]
•输入THETA2 = 135, 然后选择[OK]
–或用命令:
PCIRC,,,0,180
