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。

ANSYS四跨连续梁的内力计算教程

ANSYS四跨连续梁的内力计算教程

ANSYS四跨连续梁的内力计算四跨连续梁模型图如下所示,各个杆件抗弯刚度EI相同,利用平面梁单元分析它的变形和内力1.结构力学分析利用结构力学方法可以求出这个连续梁的剪力图和弯矩图如下这里只给出了梁的弯曲刚度相同条件,没有指定梁截面的几何参数和材料的力学性质.从结构力学分析的条件上看,这些条件对于确定梁的内力已经足够,但是对于梁的变形分析和应力计算,还需要补充材料的力学参数和截面几何参数。

所以以下分析中,假定梁的截面面积位0。

3m2,抗弯惯性矩为0.003m4,截面高度为0.1m;材料的弹性模量为1000kN/m2,泊松比为0。

3。

补充这些参数对于梁的内力没有影响,但是对于梁的变形和应力是有影响的。

2.用节点和单元的直接建模求解按照前面模型示意图布置节点和单元,在图示坐标系里定位节点的坐标和单元连接信息,以及荷载作用情况和位移约束.由于第二跨中间有两个集中力,所以在集中力位置设置两个节点。

这样,就可以将这两个集中力直接处理成节点荷载。

对于平面梁单元的节点只需输入平面上的两个坐标值,所以这里只输入节点的x坐标和y坐标.(1)指定为结构分析运行主菜单中preference偏好设定命令,然后在对话框中,指定分析模块为structural结构分析,然后单击ok按钮(2)新建单元类型运行主菜单preprocessor—element type-add/edit/delete命令,接着在对话框中单击add按钮新建单元类型(3)定义单元类型先选择单元为beam,接着选2d elastic 3,然后单击ok按钮确定,完成单元类型的选择(4)关闭单元类型的对话框回到单元类型对话框,已经新建了beam3的单元,单击对话框close按钮关闭对话框(5)定义实力常量运行主菜单preprocessor-real constants—add/edit/delete命令,接着在对话框中单击add按钮新建实力常量接着选择定义单元beam3的实力常量,选择后单击ok按钮,然后输入该单元的截面积为0。

钢筋混凝土梁ansys分析附命令流

钢筋混凝⼟梁ansys分析附命令流钢筋混凝⼟⾮线性分析2015⼤作业上海交通⼤学陈明1、参数选择梁的截⾯宽度为200mm,上部配置2Φ8受压筋,混凝⼟的净保护层厚度为25 mm(从纵向钢筋外边缘算起),箍筋两端区采⽤8@100的双肢箍,中间区取8@200 双肢箍1)梁的截⾯⾼度选300mm;2)两加载间的距离选1000mm;3)混凝⼟选C30;4)纵向受拉钢筋配筋选218;2、描述选⽤的有限元模型及单元的特点采⽤ansys软件进⾏模拟计算,钢筋混凝⼟模型采⽤分离式模型,不考虑钢筋与混凝⼟之间的相对滑移。

混凝⼟采⽤solid65单元模拟,solid65⽤于模拟三维有钢筋或⽆钢筋的混凝⼟模型。

该单元能够计算拉裂和压碎。

在混凝⼟应⽤中,该单元的实体功能可以⽤于建⽴混凝⼟模型,同时,还可⽤加筋功能建⽴钢筋混凝⼟模型。

另外,该单元还可以应⽤于加强复合物和地质材料。

该单元由⼋个节点定义,每个节点有三个⾃由度:节点坐标系的x,y,z⽅向的平动。

⾄多可以定义三种不同规格的钢筋。

钢筋单元采⽤link180单元模拟,link180是⼀个适⽤于各类⼯程应⽤的三维杆单元。

根据具体情况,该单元可以被看作桁架单元、索单元、链杆单元或弹簧单元等等。

本单元是⼀个轴向拉伸⼀压缩单元,每个节点有三个⾃由度:节点坐标系的x,y,z⽅向的平动。

本单元是⼀种顶端铰接结构,不考虑单元弯曲。

本单元具有塑性、蠕变、旋转、⼤变形和⼤应变功能。

缺省时,当考虑⼤变形时任何分析中LINK180单元都包括应⼒刚化选项。

3、描述选⽤的混凝⼟与钢筋粘结滑移本构关系的具体形式、参数等。

钢筋的应⼒应变关系曲线考虑到极限塑性应变最⼤值为0.01,钢筋本构模型采⽤多线性模型kinh,初始弹性模量为Es=200000Mpa,强化系数为0.001。

混凝⼟的应⼒应变关系曲线混凝⼟选⽤各向同性的miso模型,当计⼊下降端时,程序报错,所以只取了前⾯的上升段,⽤5段折线模拟混凝⼟应⼒应变曲线。

ansys桥梁受力分析命令流

ansys桥梁受力分析命令流

ANSYS桥梁受力分析命令流ANSYS是一款广泛应用于工程领域的有限元分析软件,它可以帮助工程师、设计师、科学家等进行各种力学或结构分析。

在工程领域中,桥梁是一种比较常见的结构,因此本文将介绍在ANSYS中进行桥梁受力分析的命令流。

1. 建立桥梁模型首先,我们需要建立桥梁模型。

在ANSYS中,可以使用多种模型建立工具,例如现在比较流行的三维CAD软件,如SolidWorks、CATIA等,均可以建立出桥梁模型。

建立好桥梁模型后,需要导入到ANSYS中进行后续分析。

2. 分配材料属性桥梁模型建立完后,需要根据实际情况为它分配材料属性。

以混凝土桥梁为例,我们可以使用“MP(材料属性)”命令为桥梁定义混凝土的相应属性。

比如,定义混凝土的弹性模量、泊松比等。

3. 设定支座约束桥梁的受力分析需要考虑桥梁的支座约束情况。

在ANSYS中,我们可以通过使用“SUPPORT”命令设定不同类型的支座约束。

4. 设定荷载桥梁承受的荷载对于力学分析至关重要,因此在进行桥梁受力分析时,必须设定荷载的种类和大小。

ANSYS提供了多种荷载设定方式,如集中荷载、分布荷载、自重荷载等。

5. 载荷应用载荷应用是桥梁受力分析中的一个关键步骤,它能够准确模拟桥梁所受荷载。

在ANSYS中,可以使用“D”命令定义荷载的应用方式,如定义一个位移荷载、力荷载等。

6. 求解过程ANSYS中提供了多种求解器,可以快速准确地解析桥梁模型受力情况。

在进行桥梁受力分析时,需要选择合适的求解器并进行计算。

ANSYS中提供了两种类型求解器,一种是基于传统矩阵进行计算的Direct Solver求解器,另一种是基于有限元模型优化的Iterative Solver求解器。

7. 结果分析在桥梁受力分析计算完成后,需要对应力和位移等结果进行分析并产生可视化的输出。

在ANSYS中,可以使用“POST1”命令来输出结果,并对结果进行后处理。

8.经过以上步骤进行受力分析后,可以得到桥梁受力的详细情况,也可以对桥梁的结构进行合理的优化。

Ansys桥梁计算

Ansys桥梁计算

桥梁计算(常用的计算方法)在Ansys单元库中,有近200种单元类型,在本章中将讨论一些在桥梁工程中常用到的单元,包括一些单元的输人参数,如单元名称、节点、自由度、实常数、材料特性、表面荷载、体荷载、专用特性、关键选项KEYOPl等。

***关于单元选择问题这是一个大问题,方方面面很多,主要是掌握有限元的理论知识.首先当然是由问题类型选择不同单元,二维还是三维,梁,板壳,体,细梁,粗梁,薄壳,厚壳,膜等等,再定义你的材料:各向同性或各向异性,混凝土的各项’参数,粘弹性等等.接下来是单元的划分与网格、精度与求解时间的要求等选择,要对各种单元的专有特性有个大概了解。

使用Ansys,还要了解Ansys的一个特点是笼统与通用,因此很多东西被掩盖到背后去了。

比如单元类型,在Solid里面看到十几种选择,Solid45, Solidl85,Solid95等,看来区别只是节点数目上。

但是实际上每种类型里还有Keyopt分成多种类型,比如最常用的线性单元Solid45,其Keyopt(1):in●cludeorexclude extradisplacement shapes,就分为非协调元和协调元,Keyopt (2):fullintegration。

rreducedintegration其实又是两种不同的单元,这样不同组合一下这个Solid45实际上是包含了6种不同单元,各有各的不同特点和用处。

因此使用Ansys要注意各单元的Keyopt选项.不同的选项会产生不同的结果。

·举例来说:对线性元例如Solid45,要想把弯曲问题计算得比较精确,必须要采用非协调模式.采用完全积分会产生剪切锁死,减缩积分又会产生零能模式(ZEM),非协调的线性元可以达到很高的精度,并且计算量比高阶刷、很多,在变形较大时,用Enhanced Strain比非协调位移模式(Enhaced Displacement)更好(Solidl85)。

ansys命令流入门教程

ansys命令流入门教程

ansys命令流入门教程在 ANSYS 中,荷载包括边界条件和作用力,对结构分析可以是以下内容:位移、力、压力、温度、重力一般可将荷载分为六类,如表 4-1 所示。

★ 荷载即可施加在几何模型(关键点、硬点、线、面、体)上,也可施加在有限元模型(节点、单元)上,或者二者混合使用。

★ 施加在几何模型上的荷载独立于有限元网格,不必为修改网格而重新加载;★ 施加在有限元模型上且要修改网格,则必须先删除荷载再修改网格,然后重新施加荷载。

★ 不管施加到何种模型上,在求解时荷载全部转换(自动或人工)到有限元模型上。

在结构分析中自由度共有7 个,自由度的方向均依从节点坐标系。

约束可施加在节点、关键点、线和面上。

一、施加自由度约束1. 节点自由度约束及相关命令(1) 对节点施加自由度约束命令:D, NODE, Lab, VALUE, VALUE2, NEND, NINC, Lab2, Lab3, Lab4, Lab5, Lab6NODE - 拟施加约束的节点号,其值可取 ALL、组件名。

Lab - 自由度标识符,如UX、ROTZ等。

如为ALL,则为所有适宜的自由度。

VALUE - 自由度约束位移值或表式边界条件的表格名称。

VALUE2 - 约束位移值的第二个数,如为复数输入时,VALUE 为实部,而 VALUE2 为虚部。

NEND,NINC - 节点编号范围和编号增量,缺省时 NEND=NODE,NINC=1。

Lab2,Lab3,Lab4,Lab5,Lab6 - 其它自由度标识符,VALUE 对这些自由度也有效。

各自由度的方向用节点坐标系确定,转角约束用弧度输入例如:D,ALL,ALL ! 对所选节点的全部自由度施加约束D,18,UX,,,,,UY,UZ ! 对节点 18 的 3 个平动自由度全部施加约束D,20,UX,1.0e-4 ! 对节点20 的UX 施加约束,且约束位移值为1.0e-4D,22,UX,0.1,,25,,UY,ROTY ! 对节点 22~25 的 UX,UY,ROTY 施加约束,且位移值均为 0.1(2) 在节点上施加对称和反对称约束命令:DSYM, Lab, Normal, KCNLab - 对称标识,如为 SYMM 则生成对称约束,如为 ASYM 则生成反对称约束。
