Mock-up 4 Preperation

leave a comment »

A nested sheet almost ready for fabrication, still without the proper fenestration.  (1) 4′ x 8′ aluminum sheet @ 1/16″ thickness.

-Nesting obviously becomes a major restriction, a possible direction for developing the connection efficiency!

Unrolled panels & folding connection…

Connection Update_Mock-up 3

leave a comment »

A few images from a third full scale mock-up, looking at 1/16″ aluminum’s folding capability.

Many thanks to Jared Laucks & Continental Signs for fabrication and photos!

Full Scale Mock-up v.2

with one comment

A few images from the second full scale mock-up…

Conclusions:

-1/8″ Aluminum may be excessive in weight for panel + tab connection

-A perforated score @ 1/8″ aluminum is very difficult to bend.  Either the panel must be 1/16″ thickness or use a channel notch, which may only allow for 90 degree folds.

-Folded connection is very clumsy looking, may go for a triangular shape as well as cut away most of the back face of the connection b/c the first fold restrict almost all of the force

FEA Analysis_Prelimary Attempt 1

with one comment

A few images showing very preliminary FEA analysis.

Axial stress with an aluminum “T” cross section.

Shear stress with an aluminum “T” cross section.

Analysis includes:

-Evenly distributed loading (Inaccurate!)

-Axial & shear loading calculation for 2 cross sections

-“T” cross section appears to resist more loading and force high stress areas to the lower right landing of the surface.

-Provides generic feedback for the surface generation….
