Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Started modeling potential designs on COMSOL.
Ordered more fans for testing along with new sheet metal with more corrugated holes.
Start angled fan tests.
Accomplishments from Previous Week
Met with sponsor to rule out ineffective designs (ie rubber grommet, padding), and discuss more realistic designs given time and cost constraints.
Collected and analyzed sound testing data into charts and incorporated into presentation.
3D Models on Solidworks of design 1 and 2.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
More sound testing using different fans. (Brandon/Peter/Jonathan)
Complete thermal analysis modeling. (Peter/Raymond/Vincent)
Start thermal/temperature testing on “hotspots” of chassis. (Brandon/Raymond)
Continue to add to final report. (Vincent)

Anything?
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
To do a rough hand calculation of the thermal analysis through the chassis. Aim for a delta of 10 degrees. Check to see if realistic.
Anything else?

N/A
Risks and Areas of Concern
EMF and MTBF issues.
Concerned with not accurately getting the 3d model to mesh together
Meshing problems and openings will affect the thermal analysis
Resources or Information Required but not Available
Thermal analysis help/tutorials
Schedule
Week 4: Wrap up chassis designs, model components in COMSOL, buy and test remaining components(fans/padding)
Week 5: Run thermal analysis software to find problem areas, run test on physical component with temperature sensors
Week 5-6: Make adjustments to design and proceed with finalized 3d model
Week 7: Have the model made and tested for final report
Week 8-9: Work on final report/website
Budget (list amount spent and amount remaining)
$117 spent on fans and padding
$1500 campus shop fee
$5883 remaining
Progress on Report and Webpage
