ANSYS基础培训练习

ANSYS基础培训练习练习主题：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OK3.打开面:编号 Utility Menu > PlotCtrls > Numbering . 设置面号on, 然后单击OK4.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 OK5.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 OK6.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 Plane6.52.50.51.80.31.0R1.4R0.4R0.7R45oSpline through six control pointsCLCLCrank pin endWrist pin endAll dimensions in inches45o0.280.40.334.754.03.257.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OK8.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 Cartesian10.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OK11.将激活的坐标系设置为总体柱坐标系: Utility Menu > WorkPlane > Change Active CS to > Global Cylindrical12.通过一系列关键点创建多义线: Main Menu > Preprocessor > -Modeling- Create > -Lines- Splines > With Options > Spline thru KPs + 如图按顺序拾取六个关键点, 然后单击 OK XV1 = 1 YV1 = 135 XV6 = 1 YV6 = 45 OK13.在关键点1和18之间创建直线: Main Menu > Preprocessor > -Modeling- Create > -Lines- Lines > Straight Line + 拾取如图的两个关键点, 然后单击 OKl,5,6l,6,7l,7,8l,8,5l,9,5l,9,6l,9,7l,9,8lsel,loc,y,0,119 ! 按位置（Y）选择立柱（线）cm,lvert,line ! 定义部件Vertical lineslsel,loc,y,120 !选择水平横梁cm,lhoriz,line !
