ANSYS实例分析75道(含结果)

ANSYS实例分析75道(含结果)【【ANSYS算例算例】】3.4.2(1)基于图形界面的桁架桥梁结构分析基于图形界面的桁架桥梁结构分析(stepbystep)下面以一个简单桁架桥梁为例，以展示有限元分析的全过程。

背景素材选自位于密执安的“OldNorthParkBridge“(1904-1988)，见图3-22。

该桁架桥由型钢组成，顶梁及侧梁，桥身弦杆，底梁分别采用3种不同型号的型钢，结构参数见表3-6。

桥长L=32m,桥高H=5.5m。

桥身由8段桁架组成，每段长4m。

该桥梁可以通行卡车，若这里仅考虑卡车位于桥梁中间位置，假设卡车的质量为4000kg，若取一半的模型，可以将卡车对桥梁的作用力简化为P1，P2和P3，其中P1=P3=5000N,P2=10000N，见图3-23。

图3-22位于密执安的“OldNorthParkBridge“(1904-1988)图3-23桥梁的简化平面模型(取桥梁的一半)表3-6桥梁结构中各种构件的几何性能参数构件惯性矩m4横截面积m2顶梁及侧梁桥身弦梁底梁解答解答以下为基于ANSYS 图形界面(GraphicUserInterface,GUI)的菜单操作流程。

ANSYS接触实例分析参考

ANSYS接触实例分析参考

ANSYS接触实例分析参考1．实例描述一个钢销插在一个钢块中的光滑销孔中。

已知钢销的半径是0.5 units, 长是2.5 units，而钢块的宽是 4 Units, 长4 Units,高为1 Units,方块中的销孔半径为0.49 units,是一个通孔。

钢块与钢销的弹性模量均为36e6，泊松比为0.3.由于钢销的直径比销孔的直径要大，所以它们之间是过盈配合。

现在要对该问题进行两个载荷步的仿真。

（1）要得到过盈配合的应力。

（2）要求当把钢销从方块中拔出时，应力，接触压力及约束力。

2．问题分析由于该问题关于两个坐标面对称，因此只需要取出四分之一进行分析即可。

进行该分析，需要两个载荷步：第一个载荷步，过盈配合。

求解没有附加位移约束的问题，钢销由于它的几何尺寸被销孔所约束，由于有过盈配合，因而产生了应力。

第二个载荷步，拔出分析。

往外拉动钢销1.7 units，对于耦合节点上使用位移条件。

打开自动时间步长以保证求解收敛。

在后处理中每10个载荷子步读一个结果。

本篇先谈第一个载荷步的计算。

下篇再谈第二个载荷步的计算。

3．读入几何体首先打开ANSYS APDL然后读入已经做好的几何体。

从【工具菜单】-->【File】-->【Read Input From】打开导入文件对话框找到ANSYS自带的文件（每个ansys都自带的）\Program Files\Ansys Inc\V145\ANSYS\data\models\block.inp【OK】后，四分之一几何模型被导入。

4．定义单元类型只定义实体单元的类型SOLID185。

至于接触单元，将在下面使用接触向导来定义。

5．定义材料属性只有线弹性材料属性：弹性模量36E6和泊松比0.36．划分网格打开MESH TOOL,先设定关键地方的网格划分份数然后在MESH TOOL中设定对两个体均进行扫略划分，在volumeSweeping中选择pick all，按下【Sweep】按钮，在主窗口中选择两个体，进行网格划分。
