ANSYS土木工程经典实例命令流大全

ANSYS土木工程经典实例命令流大全ANSYS是目前最为领先的工程仿真软件之一，广泛应用于土木工程领域。

本文将介绍一些ANSYS土木工程的经典实例以及相关的命令流，帮助工程师更好地应用该软件进行仿真分析。

1. 桥梁结构分析实例实例简介一座桥梁由多个零部件组成，包括桥墩、桥面、桥拱等。

如何分析这些零部件的受力情况，以便于对桥梁结构进行优化和改进呢？ANSYS提供了一系列的分析工具和命令流，可以帮助我们完成这项任务。

命令流详解首先需要创建一个桥梁模型，并进行网格划分。

然后利用ANSYS的各种分析工具进行仿真分析，得到桥梁各个零部件的受力情况。

在此基础上，可以进行结构优化，最终得到一个强度和稳定性都较好的桥梁结构。

以下是桥梁结构分析实例的一些关键命令流：•创建单元网格：ET, SOLID186•定义材料属性：MP, EX, NU, DENS•定义边界条件：*BOUNDARY，MP，SYM，FIX•加载边界条件：DLOAD，TYPE，P，_LOC•计算位移和应力分布：*POST1，DISPL，NF，S2. 地基基础分析实例实例简介地基基础是土木工程中的重要组成部分，承载着整个工程的重量。

如何对地基基础的承载力进行分析和计算呢？ANSYS也提供了相应的分析工具和命令流，帮助土木工程师完成这项任务。

命令流详解首先需要建立地基基础的三维模型，并进行网格划分。

然后利用ANSYS的各种分析工具进行仿真分析，计算地基基础承载力、变形等相关指标。

在此基础上，可以进行结构优化，最终得到一个承载能力和稳定性都较好的地基基础。

以下是地基基础分析实例的一些关键命令流：•创建单元网格：ET, SOLID186•定义材料属性：MP, EX, NU, DENS•定义边界条件：*BOUNDARY，MP，SYM，FIX•加载边界条件：DLOAD，TYPE，P，_LOC•计算应力分布和变形：*POST1，S，EPTO，ETA3. 挖土工程分析实例实例简介挖土工程是土木工程中的重要环节，需要对不同参数下的挖土工程进行分析和优化。

Ansys命令流大全（整理）

Ansys命令流大全（整理）1、A,P1,P2,P3,P4,P5,P6,P7,P8,P9此命令用已知的一组关键点点（P1~P9）来定义面（Area），最少使用三个点才能围成面，同时产生转围绕些面的线。

点要依次序输入，输入的顺序会决定面的法线方向。

如果超过四个点，则这些点必须在同一个平面上。

Menu Paths:Main Menu>Preprocessor>Create>Arbitrary>Through KPs2、*ABBR，Abbr,String－－定义一个缩略语．Abbr:用来表示字符串＂String＂的缩略语，长度不超过８个字符．String：将由＂Abbr＂表示的字符串，长度不超过６０个字符．3、ABBRES，Lab，Fname，Ext－从一个编码文件中读出缩略语．Lab：指定读操作的标题，NEW：用这些读出的缩略语重新取代当前的缩略语（默认）CHANGE：将读出的缩略语添加到当前缩略语阵列，并替代现存同名的缩略语．Ext：如果＂Fname＂是空的，则缺省的扩展命是＂ABBR＂．4、ABBSA V，Lab，Fname，Ext－将当前的缩略语写入一个文本文件里Lab：指定写操作的标题，若为ALL，表示将所有的缩略语都写入文件（默认）5、add, ir, ia,ib,ic,name,--,--,facta, factb, factc将ia,ib,ic变量相加赋给ir变量ir, ia,ib,ic：变量号name: 变量的名称6、Adele,na1,na2,ninc,kswp ！kswp=0时只删除掉面积本身，＝1时低单元点一并删除。

7、Adrag, nl1,nl2,nl3,nl4,nl5,nl6, nlp1,nlp2,nlp3,nlp4,nlp5,nlp6 ！面积的建立，沿某组线段路径，拉伸而成。

8、Afillt,na1,na2,rad ！建立圆角面积，在两相交平面间产生曲面，rad为半径。
