Agenda

• Top/Down modeling functionality

• Pro/WELDING

• Pro/MECHANICA sequence

• Results

• Modify Geometry to optimize design

• Final Results

• Q&A; Discussion

9-11-2010 5Pro/MECHANICA

Goal

• Userday = USERS!

• Practical issues

• Mix of Tell me, Show me

• Simple example, coat-stand design

9-11-2010 6Pro/MECHANICA

Basic Geometry

• “Coat_Stand”

9-11-2010 7Pro/MECHANICA

Skeleton

• Datum features

• Sketches

• Surfaces

• Publish Geometry

9-11-2010 8Pro/MECHANICA

Part modeling

• Create components in assembly mode

and place default; no assembly constraints

• Use Copy Geometry from Skeleton

Publish Geometry

• Surface features

• No sketches!

• Show/Erase???

9-11-2010 9Pro/MECHANICA

Pro/WELDING

• Use Intent Functionality

9-11-2010 10Pro/MECHANICA

Pro/MECHANICA sequence

• Materials

• (Midsurfaces)

• (Connections)

• Loads

• Constraints

• Analyses + RUN

• Results

9-11-2010 11Pro/MECHANICA

Materials

• Apply material on assembly level

Select top-level

assembly

9-11-2010 12Pro/MECHANICA

Midsurfaces

• Detect Shells Pairs Automatically on assembly

levelSelect top-level

assembly

9-11-2010 13Pro/MECHANICA

Connections

• Weld properties can be propagated to

Pro/MECHANICA; Weld Feature

9-11-2010 14Pro/MECHANICA

Loads

• Pro/ENGINEER parameters

9-11-2010 15Pro/MECHANICA

Mass + Weighted Links

• Apply mass to datum point (umbrella)

• Use weighted links to apply the mass to

surface regions

• Gravity

9-11-2010 16Pro/MECHANICA

Constraints

• On Intent bottom surface

• All DOF’S locked

9-11-2010 17Pro/MECHANICA

AutoGEM control

• Several new options in WF5 to “drive” the

mesh, no more “datum point seeding”

• Example: Maximum Element Size on

Intent surfaces regions

9-11-2010 Pro/MECHANICA 18

AutoGEM Review Geometry

• Fast check to inspect element creation;

notice bonding elements

9-11-2010 19Pro/MECHANICA

Mesh

• Notice how welds can be meshed

9-11-2010 20Pro/MECHANICA

Analyses

• Select correct Loadset

• Notice Inertia Relief!

9-11-2010 21Pro/MECHANICA

Analysis review

• Notice 9th polynomial order

9-11-2010 22Pro/MECHANICA

Review Polynomal Level

• Options?

– MPA?

– More Elements?

• Not relevant for this

presentation

9-11-2010 23Pro/MECHANICA

Results

• Notice new transparent fringe!

• Notice capping surface in shell models!

Modify geometry

• First idea of the engineer, more legs!

– Increase number of legs; 1 modification in

skeleton model

– Re-assign midsurfaces

– Re-assign welds (copy/paste)

9-11-2010 26Pro/MECHANICA

Re-mesh

Modify geometry

• Chief design modifications

– Modify main geometry; 1 modification in

skeleton model

– Modify leg geometry; 1 modification in

skeleton model

– Re-assign midsurfaces

Practical issues

• Lattice constructions (beams??)

• Sheet metal constructions

• Cladding optimalization

9-11-2010 34Pro/MECHANICA

Conclusion

Powerful Design Intent functionality like

– Intent functionality, (Pro/E + Pro/M)

– patterns, ref patterns

– Publish geometry / Copy Geometry (tunneling

geometry)

can really speed up your concept design process

in Pro/MECHANICA

Thank you for your attention!

• Questions?

Optimizing Mechanica

• Redefine mesh

• Use MPA, 5% convergence
