1.6 生成几何模型
生成特征点
ANSYS Main Menu: Preprocessor →Modeling →Create →Keypoints →In Active CS →依次
输入三个点的坐标：input:1(0,0),2(10,0),3(5,1) →OK
生成梁
ANSYS Main Menu: Preprocessor →Modeling →Create →Lines →lines →Straight lines
→连接两个特征点，1(0,0),2(10,0) →OK
1.7 网格划分
ANSYS Main Menu: Preprocessor →Meshing →Mesh Attributes →Picked lines →OK →选
择: SECT:1（根据所计算的梁的截面选择编号）；Pick Orientation Keypoint(s):YES→拾取：
3
#
特征点(5,1) →OK→Mesh Tool →Size Controls) lines: Set →Pick All(in Picking Menu) →input
NDIV:5 →OK (back to Mesh Tool window) → Mesh →Pick All (in Picking Menu) → Close (the
Mesh Tool window)
1.8 模型施加约束
最左端节点加约束
ANSYS Main Menu: Solution →Define Loads →Apply →Structural →Displacement →
On Nodes →pick the node at (0,0) → OK → select UX, UY,UZ,ROTX → OK
最右端节点加约束
ANSYS Main Menu: Solution →Define Loads →Apply →Structural →Displacement →
On Nodes →pick the node at (10,0) → OK → select UY,UZ,ROTX → OK
施加 y 方向的载荷
ANSYS Main Menu: Solution →Define Loads →Apply →Structural →Pressure → On
Beams →Pick All →VALI:100000 → OK
1.9 分析计算
ANSYS Main Menu: Solution →Solve →Current LS →OK(to close the solve Current Load
Step window) →OK
1.10 结果显示
ANSYS Main Menu: General Postproc →Plot Results →Deformed Shape… → select Def +
Undeformed →OK (back to Plot Results window) →Contour Plot →Nodal Solu →select: DOF
solution, UY, Def + Undeformed , Rotation, ROTZ ,Def + Undeformed→OK
1.11 退出系统
