Structural analysis of arm

1
Structural analysis of arm Model file
arm.prt Objective Calculate part displacements
and von Mises stress under boundary conditions as
shown. Note Install Procision and download
exercise parts first. A general familiarity with
Pro/E menu structure is assumed. Some menu picks
(e.g. done to close window) are not shown for
conciseness. We recommend that you review seminar
handouts and Procision manual prior to starting
this exercise. If you have any questions or
comments, please e-mail us at procision_hands_on_at_
engineering.com

OPENING PART, STARTING PROCISION
1 Make sure that Pro/E working directory is where
arm.prt is saved. Load arm.prt
2 Start Procision from Pro/E part menu
3
DEFINING MATERIAL PROPERTIES MATERIALS MENU
5 Exit material Menu, material is
saved automatically
1 Enter material definition menu from Procision
main menu
4 Enter Youngs modulus, Poissons ratio and
mass density
2 Ask for new material set
MPa
dimensionless
Tonne / mm3
3 Accept default material name MATL1 (top window)
4
DEFINING SPLIT SET SPLIT SET MENU
3 Accept default split set name SPLSET1 (top
window)
1 Enter split set definition menu from Procision
main menu
2 Ask for new split set
4 Enter material assignment menu
5
ASSIGNING MATERIAL PROPERTIES SPLIT SET MENU
5 Choose SellAssign Select all then select the
only available material MATL1
6 Choose Show Show all This will bring up a
window showing that material MATL1 (blue) has
been assigned to the entire model (see the next
slide)

ASSIGNING MATERIAL PROPERTIES SPLIT SET MENU
7 Examine material assignment window (this is
Procision post-processor window), experiment with
menus on top refer to help for more info Dynamic
keys work the same as in Pro/E.
Close window when done viewing

DEFINING SPLIT SET SPLIT SET MENU
9 Choose Set View Surfaces Restore All
8 Enter divider menu
This restores visibility of surfaces that will be
used for splitting model into subparts. These
surfaces have been created inside Procision using
Pro/E surface creation functions. Here well use
just one surface for convenient one step
splitting. More complex model generally require
several split surfaces and not necessarily planar
surfaces. Split surfaces may be created outside
of Procision as well.

DEFINING SPLIT SET SPLIT SET MENU
10 Choose Divider Select surface Pick then pick
the split surface
11 Choose Split one
12 Exit divider menu
Select Auto Hide if you wish to turn off surface
display once it has been used for splitting
9
DEFINING SPLIT SET SPLIT SET MENU
13 Display division into subpart by menu picks
as show below
14 Examine subparts window
15 Save split set SPLTSET1 Exit SPLIT SET menu
and go back to main Procision menu
Close window when done viewing
Apply shrinkage
Control magnitude of shrinkage
Note that SPLIT SET is saved independently from
MODEL

1 Enter Model menu
3 Type in model name, e.g arm_structural (top
window)
2 Choose New model
4 Choose structural problem
5 You are now in Structural model menu. Enter
concentrators menu and request automatic
detection and deployment of stress concentration
functions

6 Enter Load/BC
7 Apply immovable (built-in) supports to both end
faces of the shaft as show below. Query select
both ends using wireframe display

DEFINING MODEL MODEL MENU
10 Enter load value and angle over which it is
distributed (cosine load distribution to simulate
contact problem)
11 Return to main Procision menu (a series of
done menu picks)
14
DEFINING MODEL MODEL MENU
12 Enter accuracy menu
13 Activate Total RMS Traction BC error, accept
default 3 Activate Maximum Traction BC error,
accept default 30
14 Save your model and return to main Procision
menu
This is a standard set of accuracy requirements
for structural analysis
Maximum p order
Maximum number of iterations
15
CHECKING MODEL MAIN MENU
Check for completeness of problem definition
16
1 Start solution from Procision main menu
2 Review solver diagnostic
SOLVING MODEL MAIN MENU

Once model is solved and diagnostic window
closed, you are in results menu. Now, review
options available here. In particular examine
displacement and stress results, then BC errors
displacement results mm

SAVING RESULTS RESULT MENU
When done with results analysis, exit RESULT menu
and save your results accepting default RESULT1
name.
