结构稳定问题一般分为两类:★第一类失稳:又称平衡分岔失稳、分枝点失稳、特征值屈曲分析。

结构失稳时相应的载荷可称为屈曲载荷、临界载荷、压屈载荷或平衡分枝载荷。

★第二类失稳:结构失稳时,平衡状态不发生质变,也称极值点失稳。

结构失稳时相应的载荷称为极限载荷或压溃载荷。

●跳跃失稳:当载荷达到某值时,结构平衡状态发生一明显的跳跃,突然过渡到非邻近的另一具有较大位移的平衡状态。

可归入第二类失稳。

★结构弹性稳定分析= 第一类稳定问题ANSYS 特征值屈曲分析(Buckling Analysis)。

★第二类稳定问题ANSYS 结构静力非线性分析,无论前屈曲平衡状态或后屈曲平衡状态均可一次求得,即“全过程分析”。

这里介绍ANSYS 特征值屈曲分析的相关技术。

在本章中如无特殊说明,单独使用的“屈曲分析”均指“特征值屈曲分析”。

7.1 特征值屈曲分析的步骤①创建模型②获得静力解③获得特征值屈曲解④查看结果一、创建模型注意三点:⑴仅考虑线性行为。

若定义了非线性单元将按线性单元处理。

刚度计算基于初始状态(静力分析后的刚度),并在后续计算中保持不变。

⑵必须定义材料的弹性模量或某种形式的刚度。

非线性性质即便定义了也将被忽略。

⑶单元网格密度对屈曲载荷系数影响很大。

例如采用结构自然节点划分时(一个构件仅划分一个单元)可能产生100% 的误差甚至出现错误结果,尤其对高阶屈曲模态的误差可能更大,其原因与形成单元应力刚度矩阵有关。

经验表明,仅关注第1 阶屈曲模态及其屈曲载荷系数时,每个自然杆应不少于 3 个单元。

ansys结构分析入门-命令流

1 ANSYS概述1.1 ANSYS简介ANSYS是一种广泛的商业套装工程分析软件。

所谓工程分析软件,主要是在机械结构系统受到外力负载所出现的反应,例如应力、位移、温度等,根据该反应可知道机械结构系统受到外力负载后的状态,进而判断是否符合设计要求。

一般机械结构系统的几何结构相当复杂,受的负载也相当多,理论分析往往无法进行。

想要解答,必须先简化结构,采用数值模拟方法分析。

由于计算机行业的发展,相应的软件也应运而生,ANSYS软件在工程上应用相当广泛,在机械、电机、土木、电子及航空等领域的使用,都能达到某种程度的可信度,颇获各界好评。

使用该软件,能够降低设计成本,缩短设计时间。

到80年代初期,国际上较大型的面向工程的有限元通用软件主要有:ANSYS, NASTRAN, ASKA, ADINA, SAP等。

以ANSYS为代表的工程数值模拟软件,是一个多用途的有限元法分析软件,它从1971年的2.0版本与今天的5.7版本已有很大的不同,起初它仅提供结构线性分析和热分析,现在可用来求结构、流体、电力、电磁场及碰撞等问题的解答。

它包含了前置处理、解题程序以及后置处理,将有限元分析、计算机图形学和优化技术相结合,已成为现代工程学问题必不可少的有力工具。

1.2ANSYS软件主要功能ANSYS软件是融结构、热、流体、电磁、声学于一体的大型通用有限元软件,可广泛的用于核工业、铁道、石油化工、航空航天、机械制造、能源、汽车交通、国防军工、电子、土木工程、生物医学、水利、日用家电等一般工业及科学研究。

该软件提供了不断改进的功能清单,具体包括:结构高度非线性分析、电磁分析、计算流体力学分析、设计优化、接触分析、自适应网格划分及利用ANSYS参数设计语言扩展宏命令功能。

1.3ANSYS软件主要特点主要技术特点:∙唯一能实现多场及多场耦合分析的软件∙唯一实现前后处理、求解及多场分析统一数据库的一体化大型FEA软件∙唯一具有多物理场优化功能的FEA软件∙唯一具有中文界面的大型通用有限元软件∙强大的非线性分析功能∙多种求解器分别适用于不同的问题及不同的硬件配置∙支持异种、异构平台的网络浮动,在异种、异构平台上用户界面统一、数据文件全部兼容∙强大的并行计算功能支持分布式并行及共享内存式并行∙多种自动网格划分技术∙良好的用户开发环境支持的图形传递标准:∙SAT∙Parasolid∙STEP与CAD软件的接口∙Unigraphics∙Pro/ENGINEER∙I-Deas∙Catia∙CADDS∙SolidEdge∙SolidWorks1.4 运行环境(ANSYS5.7)Computer: Pentium-class systemMemory (RAM): 64 MB以上Hard Disk: 500MB以上自由空间.Operating System: Microsoft Windows 2000, Windows NT 4.0 (SP 5 or higher) or Windows 98 Graphics: A Windows 2000/NT 4.0 or 98 supported Graphics Card, capable of 1024x768 in High Color (16-bit).A 17 inch monitor (or larger) compatible with the above mentioned card is recommended.2ANSYS 的基本使用2.1 ANSYS环境简介ANSYS有两种模式:一种是交互模式(Interactive Mode),另一个是非交互模式(Batch Mode)。

ANSYS结构分析单元功能与特性/可以组成一一些命令,一般是一种总体命令(session),三十也有特殊,比如是处理/POST1! 是注释说明符号,,与其他软件的说明是一样的,ansys不作为命令读取,* 此符号一般是APDL的标识符,也就是ansys的参数化语言,如*do ,,,*enddo等等NSEL的意思是node select,即选择节点。

s就是select,选择。

DIM 是定义数组的意思。

array 数组。

ANSYS结构分析指南结构线性静力分析

ANSYS结构分析指南结构线性静力分析

ANSYS结构分析指南第二章结构线性静力分析2.1 静力分析的定义静力分析计算在固定不变载荷作用下结构的响应,它不考虑惯性和阻尼影响--如结构受随时间变化载荷作用的情况。

可是,静力分析可以计算那些固定不变的惯性载荷对结构的影响(如重力和离心力),以及那些可以近似为等价静力作用的随时间变化载荷(如通常在许多建筑规范中所定义的等价静力风载和地震载荷)的作用。

静力分析用于计算由那些不包括惯性和阻尼效应的载荷作用于结构或部件上引起的位移、应力、应变和力。

固定不变的载荷和响应是一种假定,即假定载荷和结构响应随时间的变化非常缓慢。

静力分析所施加的载荷包括:外部施加的作用力和压力稳态的惯性力(如重力和离心力)强迫位移温度载荷(对于温度应变)能流(对于核能膨胀)关于载荷,还可参见§2.3.4。

2.2 线性静力分析与非线性静力分析静力分析既可以是线性的也可以是非线性的。

非线性静力分析包括所有类型的非线性:大变形、塑性、蠕变、应力刚化、接触(间隙)单元、超弹性单元等。

本章主要讨论线性静力分析。

对非线性静力分析只作简单介绍,其详细论述见《ANSYS Structural Analysis Guide》§8。

2.3 静力分析的求解步骤2.3.1 建模首先用户应指定作业名和分析标题,然后通过PREP7 前处理程序定义单元类型、实常数、材料特性、模型的几何元素。

这些步骤是大多数分析类型共同的,并已在《ANSYS Basic Analysis Guide》§1.2 论述。

有关建模的进一步论述,见《ANSYS Modeling and Meshing Guide》。

2.3.1.1 注意事项在进行静力分析时,要注意如下内容:1、可以采用线性或非线性结构单元。

2、材料特性可以是线性或非线性,各向同性或正交各向异性,常数或与温度相关的:必须按某种形式定义刚度(如弹性模量EX,超弹性系数等)。

对于惯性载荷(如重力等),必须定义质量计算所需的数据,如密度DENS。

(完整版)ANSYS最常用命令流+中文注释(超级大全)

ANSYS最常用命令流+中文注释VSBV, NV1, NV2, SEPO, KEEP1, KEEP2 —Subtracts volumes from volumes,用于2个solid相减操作,最终目的是要nv1-nv2=?通过后面的参数设置,可以得到很多种情况:sepo项是2个体的边界情况,当缺省的时候,是表示2个体相减后,其边界是公用的,当为sepo的时候,表示相减后,2个体有各自的独立边界。

keep1与keep2是询问相减后,保留哪个体?当第一个为keep时,保留nv1,都缺省的时候,操作结果最终只有一个体,比如:vsbv,1,2,sepo,,keep,表示执行1-2的操作,结果是保留体2,体1被删除,还有一个1-2的结果体,现在一共是2个体(即1-2与2),且都各自有自己的边界。

如vsbv,1,2,,keep,,则为1-2后,剩下体1和体1-2,且2个体在边界处公用。

2 启动Ansys Workbench,在界面中选择Simulation启动DS模块。

3 导入三维模型,操作步骤按下图进行,单击“Geometry”,选择“From File”。

从弹出窗口中选择三维模型文件,如果文件格式不符,可以把三维图转换为“.stp”格式文件,即可导入,如下图所示。

4 选择零件材料:文件导入后界面如下图所示,这时,选择“Geometry”下的“Part”,在左下角的“Details of ‘Part’”中可以调整零件材料属性。

5 划分网格:如下图,选择“Project”树中的“Mesh”,右键选择“Generate Mesh”即可。

【此时也可以在左下角的“Details of‘Mesh’”对话框中调整划分网格的大小(“Element size”项)】。

生成网格后的图形如下图所示:6 添加分析类型:选择上方工具条中的“New Analysis”,添加所需做的分析类型,此例中要做的是静力分析,因此选择“Static Structural”,如下图所示。

7 添加固定约束:如下图所示,选择“Project”树中的“Static Structural”,右键选择“Insert”中的“Fixed Support”。

这时左下角的“Details of ‘Fixed Support’”对话框中“Geometry”被选中,提示输入固定支撑面。

本例中固定支撑类型是面支撑,因此要确定图示6位置为“Face”,【此处也可选择“Edge”来选择“边”】然后按住“CTRL”键,连续选择两个孔面为支撑面,按“Apply”确认,如下图所示。

8 添加载荷:选择“Project”树中的“Static Structural”,右键选择“Insert”中的“Force”,如下图所示。

ANSYS结构分析指南 p-方法结构静力分析

ANSYS结构分析指南 p-方法结构静力分析

ANSYS结构分析指南第六章p-方法结构静力分析6.1 p-方法分析的定义p-方法得到按照用户指定精度的结果,如位移、应力或应变等。

为了计算这些结果,p-方法操作(用于近似真实解的)有限元形函数的多项式水平(p-水平)。

其工作原理是,在一定的网格密度下,按照给定的p-水平求解,然后逐步增大p-水平,对该网格再次求解。

每一次进行这种迭代后,把其结果与一组收敛准则进行比较。

用户可以指定收敛判据中包括模型某一点或某些点的位移、转角、应力、应变,以及总体应变能。

p-水平越高,则有限元解越接近真实解。

为了利用p-方法的功能,用户并不需要只限于在p-方法生成的网格范围内工作。

在网格生成时考虑了p-单元的应用时,p-方法最为有效,但并不要求必须如此。

当然,用户可以对模型采用p-单元来建立和分网,也可以对为h-单元生成的网格(由ANSYS 或CAD 软件包生成)来进行p-方法求解,但是该单元应该至少有中节点。

这样,不论用什么方法生成网格,都可以利用p-方法的优点。

p-方法可以对任意网格自动改进其结果。

6.2 应用p-方法的优点对于结构线性静力分析而言,p-方法求解选项提供了比传统h-方法(已在以前各章论述)更多的优点。

最显著的优点是,不需用户严格地控制网格,就可以使求解提高到合适的精度水平。

如果用户是有限元分析的新手,或者在网格设计时没有坚实的基础知识,你可能更喜欢这种方法,因为这种方法减轻了用户手工设计精确网格的负担。

此外,p-方法自适应加密方法提供了比h-方法更精确的误差评估,可以按局部计算,也可以按总体计算(如某点处的应力,而不是应变能)。

例如,用户需要获得在某点上的高精度解(如断裂或疲劳组件),p-方法为在这些点上取得要求精度的结果提供了极佳的方法。

6.3 应用p-方法用p-方法进行静力分析分为四个步骤:1、选择p-法;2、建模;3、施加载荷和求解;4、检查结果。

6.3.1 选择p-方法可用二种方法激活p-方法求解程序。
