Truss Analysis with ANSYS Guide

This document provides instructions for using ANSYS to design and perform a structural analysis of a truss. It describes the steps to (1) define element types, material properties, and real constants, (2) model the truss geometry by creating nodes and connecting elements, (3) apply boundary conditions and loads, (4) solve the model, and (5) review results using post-processing tools to plot deformed node positions. The specific example analyzes a 14-node truss with given material properties, cross-sectional area, and applied forces at two nodes.

DESIGN AND PERFORM STRUCTURAL ANALYSYS OF A TRUSS USING ANSYS 9

DESIGN AND PERFORM STRUCTURAL ANALYSIS OF A TRUSS USING


ANSYS (mechanical APDL)
Pre-processor:
A typical analysis in ANSYS begins with pre-processing where data such as the
geometry, materials and element types are specified.
Set preferences: The preferences dialog box allows to choose the desired
engineering discipline for context filtering of menu choices.
- Turn on structural.
- Select structural discipline options as h-method.

Define element types and options: Select proper element from this dialog box.
Pre-processor →Element type →Add/Edit/Delete
Select Beam Link-2D spar-1.

Define real constants: Real constant provide additional geometry information.


In this problem links of the entire truss configuration is of same cross-sectional
area. Cross section area = 0.01m2.

Define material properties: Material properties are constitutive properties of a


material such as young’s modulus and poisson’s ratio. Assume the material as
isotropic.
In this problem Young’s modulus = 2x107N/m2
Poisson’s ratio = 0.27

Modelling: This problem has Discretised into 24 elements formed from 14


nodes. In the world co-ordinate system the co-ordinates of the fourteen nodes
are as follows.
1-(0,0), 2-(80,0) , 3-(10,30) , 4-(40,30) , 5-(70,30) , 6-(20,60) , 7-(40,60) ,
8(60,60) , 9-(20,100) , 10-(60,100) , 11-(60,140) , 12-(100,140) , 13-
(140,140) , 14-(100,110) . All dimensions are in meters only.
Pre-processor →Modelling →Create →Nodes → In-Active CS
After entering co-ordinates of each node click on Apply to enter next
node click on O.K after entering the last node.

Elements: In this problem link is assumed as isotropic so no need to set the


element attributes.
Pre-processor →Modelling →Create →Elements →Thru-Nodes
Select two nodes to create an element. Then click on Apply and repeat the
same procedure for the complete truss.

Solution:
Boundary conditions(Displacement constraints) and loads can be applied in
this stage.
i) Displacement Constraints :
Solution → Loads → Apply → Structural → Displacements → On Nodes
Select Node-1 as displacement constraint and click on Apply . In this
dialog box click on All DOF and Click on O.K.
Select Node-2 and click on Apply . In this dialog box click on UY and
click on O.K .

ii) Applying forces:


Solution → Loads → Apply →Force/Moment on Nodes
Select Node-13 and click on Apply . In this dialog box select UX and
enter UX= 16525N. Again pick node-13 UY= -41298N.

iii) Solve:
Solution → Solve → Current L.S

Post processor:
Post processor is used to review the results through graphics display and tabular
listing.
General Post processor →Plot Results →Nodal Solution
In this dialog box select items to be contoured as DOF Solution and translation
as USUM.
Item to be plotted is Def + Undeformed. Then click on O.K.
