根据ANSYS的桥梁分析
钢桁架桥静力受力分析对一架钢桁架桥进行具体静力受力分析，分别采用GUI方式和命令流方式。
A 问题描述图6-15 钢桁架桥简图已知下承式简支钢桁架桥桥长72米，每个节段12米，桥宽10米，高16米。
设桥面板为0.3米厚的混凝土板，当车辆行驶于桥梁上面时，轴重简化为一组集中力作用于梁上，来计算梁的受力情况。
桁架杆件规格有三种，见下表：杆件截面号形状规格端斜杆 1 工字形400×400×16×16上下弦 2 工字形400×400×12×12 横向连接梁 2 工字形400×400×12×12其他腹杆 3 工字形400×300×12×12所用材料属性如下表：表6-3 材料属性参数钢材混凝土弹性模量EX 2.1×1011 3.5×1010泊松比PRXY 0.3 0.1667密度DENS 7850 2500B GUI操作方法1.创建物理环境1）过滤图形界面：GUI：Main Menu> Preferences，弹出“Preferences for GUI Filtering”对话框，选中“Structural”来对后面的分析进行菜单及相应的图形界面过滤。
2）定义工作标题：GUI：Utility Menu> File> Change Title，在弹出的对话框中输入“Truss Bridge StaticAnalysis”，单击“OK”。
如图6-16（a）。
指定工作名：GUI：Utility Menu> File> Change Jobname，弹出一个对话框，在“Enter new Name”后面输入“Structural”，“New log and error files”选择yes，单击“OK”。
如图6-16（b）。

（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。
同理，将v换成a 及l是对面和线进行减操作！mp,lab, mat, co, c1,…….c4 定义材料号及特性lab: 待定义的特性项目（ex,alpx,reft,prxy,nuxy,gxy,mu,dens）ex: 弹性模量nuxy: 小泊松比alpx: 热膨胀系数reft: 参考温度reft: 参考温度prxy: 主泊松比gxy: 剪切模量mu: 摩擦系数dens: 质量密度mat: 材料编号（缺省为当前材料号）co: 材料特性值，或材料之特性，温度曲线中的常数项c1-c4: 材料的特性-温度曲线中1次项，2次项，3次项，4次项的系数定义DP材料：首先要定义EX和泊松比：MP，EX，MA T，……MP，NUXY，MAT，……定义DP材料单元表（这里不考虑温度）：TB，DP，MA T进入单元表并编辑添加单元表：TBDATA，1，CTBDATA，2，ψTBDATA，3，……如定义：EX=1E8，NUXY=0.3，C=27，ψ=45的命令如下：MP，EX，1，1E8MP，NUXY，1，0.3TB，DP，1TBDATA，1，27TBDATA，2，45这里要注意的是，在前处理的最初，要将角度单位转化到“度”，即命令：*afun,degVSEL, Type, Item, Comp, VMIN, VMAX, VINC, KSWP Type，是选择的方式，有选择（s）,补选（a），不选(u)，全选(all)、反选（inv）等,其余方式不常用Item, Comp 是选取的原则以及下面的子项如volu 就是根据实体编号选择，loc 就是根据坐标选取，它的comp就可以是实体的某方向坐标！其余还有材料类型、实常数等MIN, VMAX, VINC，这个就不必说了吧！,例：vsel,s,volu,,14vsel,a,volu,,17,23,2上面的命令选中了实体编号为14，17，19，21，23的五个实体VDELE, NV1, NV2, NINC, KSWP: 删除未分网格的体nv1:初始体号nv2:最终的体号ninc:体号之间的间隔kswp=0:只删除体kswp=1:删除体及组成关键点,线面如果nv1=all,则nv2,ninc不起作用其后面常常跟着一条显示命令VPLO,或aplo,nplo,这个湿没有参数的命令，输入后直接回车，就可以显示刚刚选择了的体、面或节点，很实用的哦！Nsel, type, item, comp, vmin, vmax, vinc, kabs 选择一组节点为下一步做准备Type: S: 选择一组新节点（缺省）R: 在当前组中再选择A: 再选一组附加于当前组U: 在当前组中不选一部分All: 恢复为选中所有None: 全不选Inve: 反向选择Stat: 显示当前选择状态Item: loc: 坐标node: 节点号Comp: 分量Vmin,vmax,vinc: ITEM范围Kabs: “0” 使用正负号“1”仅用绝对值下面是单元生死第一个载荷步中命令输入示例：!第一个载荷步TIME,... !设定时间值（静力分析选项）NLGEOM,ON !打开大位移效果NROPT,FULL !设定牛顿－拉夫森选项ESTIF,... !设定非缺省缩减因子（可选）ESEL,... !选择在本载荷步中将不激活的单元EKILL,... !不激活选择的单元ESEL,S,LIVE !选择所有活动单元NSLE,S !选择所有活动结点NSEL,INVE !选择所有非活动结点（不与活动单元相连的结点）D,ALL,ALL,0 !约束所有不活动的结点自由度（可选）NSEL,ALL !选择所有结点ESEL,ALL !选择所有单元D,... !施加合适的约束F,... !施加合适的活动结点自由度载荷SF,... !施加合适的单元载荷BF,... !施加合适的体载荷SA VESOLVE请参阅TIME,NLGEOM,NROPT,ESTIF,ESEL,EKILL,NSLE,NSEL,D, F,SF和BF命令得到更详细的解释。

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 分析的命令流(APDL语言)
ANSYS 分析的命令流（APDL语言）前面分析的过程都是基于ANSYS用户图形界面(GUI命令流)形式，GUI 形式非常的直观明了，分析过程中通常会采用此种的分析方式。
但是这种分析方式会有一个缺点，就是当我们操作失误时候，没有后退的功能，因此我们不得不重新操作，这样就会给分析带来很多的麻烦。
但如果以命令流的形式进行计算的话就能很容易的减少这些麻烦。

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。
