工字梁端面受力分析

一工字梁型号为32a，跨度1000m，求其在集中力P1=8000N和P2=5000N作用下O点的挠度。该工字梁材料的弹性模量为220Gpa，泊松比为0.3。

问题分析：选择梁单元进行分析。

求解步骤

1.定义工作名和工作标题

选择utility menu/file/change jobname

选择utility menu/file/change title

2.定义单元类型

Main menu/preprocessor/element type/add/edit/delete

Main menu/preprocessor/real constants/add/edit/delete

3.定义材料性能参数

Main menu/preprocessor/material props/material models

Main menu/preprocessor/sections/beam/common sectns

4.创建几何模型、网格划分

Main menu/preprocessor/modeling/create/keypoints/in active cs

同样创建关键点2（1,0,0）

Main menu/preprocessor/modeling/create/lines/lines/straight line

依次连接1,2, 创建线段。

Main menu/preprocessor/meshing/size cntrls/manuasize/lines/all lines

Main menu/preprocessor/meshing/mesh/line 单击pick all

5. 加载求解

Main menu/solution/analysis type/new analysis 选择static

Main menu/solution/define loads/apply/structural/displacement/on keypoints 拾取关键点1

Main menu/solution/define loads/apply/structural/force/moment/on keypoint 拾取关键点2

Main menu/solution/solve /current ls ansys进行求解6. 查看求解结果

Main menu/general postproc/plot result/deformed shape
