• Summary

Computer Simulation

• Modeling– Computer Aided Design

• 3D part drawings were constructed• Parts were then assembled as required

– Finite Elemental Analysis• Stress analysis was performed on the original

design and the new designs proposed• Maximum principal stress was compared for each

design

Computer Aided Design

• Autodesk Inventor

Computer Simulation• Original Design 100 psi 100lbf Couple

Computer Simulation Cont’d• 2x6 Design 100 psi 100lbf Couple

Computer Simulation Cont’d• 1x6 Design with Bracing and Glue• 100 psi 100lbf Couple

Packaging

• Procured Boxes, bubble wrap, and tape

• Provide Client with 2 options– Option A

• Smaller box therefore cheaper shipping cost• Much more assembly required

– Option B• Larger box therefore more expensive to ship• Less Assembly required
