问题描述:
这是一个关于角支架的单载荷步的结构静力分析。如图所示,左上角的销孔由于焊接而被固定死。右下角的销孔上作用一分布力。本问题的目标是熟悉ANSYS分析的基本过程。使用的是美国的单位体系。
材料的杨氏模量为30E6 psi,泊松比0.27。
几何建模:
第一步:定义矩形
Main Menu Preprocessor Modeling Create Areas Rectangle By Dimensions
Enter the following:
X1 = 0 ,X2 = 6,Y1 = -1,Y2 = 1
Apply to create the first rectangle.
Enter the following:
X1 = 4,X2 = 6,Y1 = -1,Y2 = -3
OK to create the second rectangle and close the dialog box.
第二步:更改绘图属性和重绘。
Utility Menu Plot Ctrls Numbering
Turn on area numbers.
OK to change controls, close the dialog box, and replot.
Toolbar: SAVE_DB.
第三步:更改工作平面为极坐标系并创建第一个圆
Utility Menu WorkPlane Display Working Plane (toggle on)
Utility Menu WorkPlane WP Settings
Click on Polar.
Click on Grid and Triad.
Enter 0.1 for snap increment.
OK to define settings and close the dialog box.
Main Menu Preprocessor Modeling Create Areas Circle Solid Circle
Pick center point at:WP X = 0,WP Y = 0
Move mouse to radius of 1 and click left button to create circle.
OK to close picking menu.
Toolbar: SAVE_DB.
第四步:移动工作平面并创建第二个圆
Utility Menu WorkPlane Offset WP to Keypoints
Pick keypoint at lower left corner of rectangle.
Pick keypoint at lower right of rectangle.
OK to close picking menu.
Main Menu Preprocessor Modeling Create Areas Circle Solid Circle
Pick center point at:WP X = 0,WP Y = 0
Move mouse to radius of 1 and click left button to create circle.
OK to close picking menu.
Toolbar: SAVE_DB.
第五步:增加面
Main Menu Preprocessor Modeling Operate Booleans Add Areas
Pick All for all areas to be added.
Toolbar: SAVE_DB.
第六步:创建线倒角
Utility Menu PlotCtrls Numbering
Turn on line numbering.
OK to change controls, close the dialog box, and automatically replot.
Utility Menu WorkPlane Display Working Plane (toggle off)
Main Menu Preprocessor Modeling Create Lines Line Fillet
Pick lines 17 and 8.
OK to finish picking lines (in picking menu).
Enter 0.4 as the radius.
OK to create line fillet and close the dialog box.
Utility Menu Plot Lines
第七步:创建倒角面
