ansys静力分析实例1
结构分析实验指导书
1.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。
材料的氏模量为30E6 psi，泊松比0.27。
2.几何建模：
第一步：定义矩形
1.Main Menu> Preprocessor> Modeling> Create> Areas> Rectangle> By
Dimensions
2.Enter the following:
X1 = 0 ,X2 = 6,Y1 = -1,Y2 = 1
3.Apply to create the first rectangle.
4.Enter the following:
X1 = 4,X2 = 6,Y1 = -1,Y2 = -3
5.OK to create the second rectangle and close the dialog box.
第二步：更改绘图属性和重绘。
1.Utility Menu> Plot Ctrls> Numbering
2.Turn on area numbers.
3.OK to change controls, close the dialog box, and replot.
4.Toolbar: SAVE_DB.
第三步：更改工作平面为极坐标系并创建第一个圆
1.Utility Menu> WorkPlane> Display Working Plane (toggle on)
2.Utility Menu> WorkPlane> WP Settings
3.Click on Polar.
4.Click on Grid and Triad.
5.Enter 0.1 for snap increment.
6.OK to define settings and close the dialog box.
7.Main Menu> Preprocessor> Modeling> Create> Areas> Circle> Solid
Circle
8.Pick center point at:WP X = 0，WP Y = 0
9.Move mouse to radius of 1 and click left button to create circle.
10.OK to close picking menu.
11.Toolbar: SAVE_DB.
第四步：移动工作平面并创建第二个圆
1.Utility Menu> WorkPlane> Offset WP to> Keypoints
2.Pick keypoint at lower left corner of rectangle.
3.Pick keypoint at lower right of rectangle.
4.OK to close picking menu.
5.Main Menu> Preprocessor> Modeling> Create> Areas> Circle> Solid
Circle
6.Pick center point at:WP X = 0，WP Y = 0
7.Move mouse to radius of 1 and click left button to create circle.
8.OK to close picking menu.
9.Toolbar: SAVE_DB.
第五步：增加面
1.Main Menu> Preprocessor> Modeling> Operate> Booleans> Add> Areas
2.Pick All for all areas to be added.
3.Toolbar: SAVE_DB.
第六步：创建线倒角
1.Utility Menu> PlotCtrls> Numbering
2.Turn on line numbering.
3.OK to change controls, close the dialog box, and automatically
replot.
4.Utility Menu> WorkPlane> Display Working Plane (toggle off)
5.Main Menu> Preprocessor> Modeling> Create> Lines> Line Fillet
6.Pick lines 17 and 8.
7.OK to finish picking lines (in picking menu).
8.Enter 0.4 as the radius.
9.OK to create line fillet and close the dialog box.
10.Utility Menu> Plot> Lines
第七步：创建倒角面
1.Utility Menu> PlotCtrls> Pan, Zoom, Rotate
2.Click on Zoom button.
3.Move mouse to fillet region, click left button, move mouse out and
click again.
4.Main Menu> Preprocessor> Modeling> Create> Areas> Arbitrary> By
Lines
5.Pick lines 4, 5, and 1.
6.OK to create area and close the picking menu.
7.Click on Fit button.
8.Close the Pan, Zoom, Rotate dialog box.
9.Utility Menu> Plot> Areas
10.Toolbar: SAVE_DB.
第八步：将面添加到一起
1.Main Menu> Preprocessor> Modeling> Operate> Booleans> Add> Areas
2.Pick All for all areas to be added.
3.Toolbar: SAVE_DB.
第九步：创建第一个销孔
1.Utility Menu> WorkPlane> Display Working Plane (toggle on)
2.Main Menu> Preprocessor> Modeling> Create> Areas> Circle> Solid
Circle
3.Pick center point at: WP X = 0，WP Y = 0
4.Move mouse to radius of .4 (shown in the picking menu) and click
left button to create circle.
