Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Major choices have been made regarding our final CAD design, with a set final design being close to completion.
MATLAB and FEA analysis are both being used to aid in completion of final design.
Materials are being ordered this week so manufacturing can begin.
Accomplishments from Previous Week
Final stiffener design will be our grid design.
Stiffeners will be manufactured using either extruded I-beams or (most likely) stamped sheet metal.
Entire door will be formed out of Aluminum.
Kakeru has made significant progress on the MATLAB optimization code.
Code will be updated and modified to produce more accurate results.
FEA analysis confirmed that creating a scale door model under the max weight and deflection was doable (see sponsor comments).
The Proof of Concept presentation was given to our section.
The First Draft of the final project was completed.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Shane will take charge of researching raw materials and manufacturing items that need to be purchased this week. Will ideally order enough materials to create 2 scale models of the door.
Joao is working on completing the finalized CAD model of our door. This door will be to scale and will have the correct curvature (rather than the flat model used up until this point).
Kakeru will continue updating the MATLAB optimization code. He is also planning on looking into Topology Optimization and its possible application in the project.
Ahmed is continuing to focus on the FEA analysis of our CAD models, and will assist Kakeru in any Topology Optimization efforts.
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Even though our team was leaning most towards riveting the stiffeners to our panels, our sponsors recommended looking into industrial bonding agents as well. With both stamped sheet and I-beams, riveting and bonding are possible.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
We did not have a private meeting with the professor last week, the main source of feedback was from the Proof of Concept Presentation.
Professor heavily pushed for our consideration of Stamped Sheet stiffeners for our design, which we have incorporated into our latest CAD models.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Feedback from our last presentation was very positive, with top scores in most categories.
Risks and Areas of Concern
With our designs almost complete, our primary areas of concern are now mainly manufacturing related.
Creating a door that is both to scale and curved will be challenging, and will require advice from the machine shop staff.
Resources or Information Required but not Available
At this point in time, most all of the missing geometric constraints of the door have been accounted for.
One notable exception, the location the 16 fixture points needed to "properly" complete our FEA analysis as per Collins' request.
Once these points are provided by our sponsors, our FEA results will become more geometrically valid.
Schedule
This week's major milestone will involve the ordering of materials
The Gantt chart has been updated as of May 5.
Budget (list amount spent and amount remaining)
None of the budget has been spent as of May 5th, but this will change this week once materials are purchased.
Progress on Report and Webpage
The first draft of the report was completed last Friday night.
