ANSYS自下向上實體建模建立連桿模型

1、EX3.練習(xí)主題：自下向上實體建模建立連桿模型練習(xí)目的：熟悉從下向上建模的過程1. 進入ANSYS工作目錄，將 "c-rod ”作為jobname。2. 創(chuàng)建兩個圓面：-Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > ByDime nsions .? RAD1 = 1.4? RAD2 = 1? THETA1 = 0? THETA2 = 180, 單擊Apply?然后設(shè)置THETA1 = 45,再單擊OK3. 打開面:編號-Utility Menu > PlotCtrls &g

2、t; Numbering .?設(shè)置面號on,然后單擊OK4. 創(chuàng)建兩個矩形面：一； 1- Main Menu > Preprocessor > -Modeling- Create > -Areas- Rectangle > ByDime nsions .? X1 = -0.3, X2 = 0.3, Y1 = 1.2, Y2 = 1.8,單擊Apply? X1 = -1.8, X2 = -1.2, Y1 = 0, Y2 = 0.3,單擊OK5. 偏移工作平面到給定位置（X=6.5）:-Utility Menu > WorkPlane > Offset WP t

3、o > XYZ Locations +?在ANSYS輸入窗口輸入6.5? OK6. 將激活的坐標系設(shè)置為工作平面坐標系-Utility Menu > WorkPlane > Change Active CS to > Working Plane54.083.234756.5All dimensions in inchesthrough six7. 創(chuàng)建另兩個圓面-Main Menu > Preprocessor > -Modeling- Create > -Areas- Circle > ByDime nsions .? RAD1 = 0.7?

4、RAD2 = 0.4? THETA1 = 0? THETA2 = 180, 然后單擊Apply?第二個圓THETA2 = 135, 然后單擊OK8. 對面組分別執(zhí)行布爾運算：- Main Menu > Preprocessor > -Modeling- Operate > -Booleans- Overlap >Areas +?首先選擇左側(cè)面組，單擊Apply?然后選擇右側(cè)面組，單擊OK9. 將激活的坐標系設(shè)置為總體笛卡爾坐標系：-Utility Menu > WorkPlane > Change Active CS to > Global Carte

5、sian10. 定義四個新的關(guān)鍵點：- Main Menu > Preprocessor > -Modeling- Create > Keypoints > In ActiveCS?第一個關(guān)鍵點?第二個關(guān)鍵點?第三個關(guān)鍵點?第四個關(guān)鍵點,X=2.5, 丫=0.5,X=3.25, 丫=0.4,X=4, Y=0.33,單擊Apply單擊Apply單擊Apply,X=4.75, Y=0.28, 單擊OK11. 將激活的坐標系設(shè)置為總體柱坐標系-Utility Menu > WorkPlane > Change Active CS to > Global Cylindrical12. 通過一系列關(guān)鍵點創(chuàng)建多義線：-Main Menu > Preprocessor > -Modeling- Create > -Lines- Splines > WithOptions > Spline thru KPs +?
