Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Analysis, Design, and Fabrication still being done
Must do impact head tests
Obtained foam, determined how it deforms under load-- this is helpful for calculations and modal analysis
Accomplishments from Previous Week
Obtained foam from ATA (Saved $1000)
ATA was very satisfied with all assumptions, calculations, and overall progress made so far
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Design and test impact heads (Roy/Troy)
order delrin (Leighy)
recalculations with new mass of excitation surface (Troy)
Determine characteristics of foam from ATA (Leighy)
Optistruct on foam and fixture plate (Sam)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Small upward angle for test head impact is fine (look more into it, but if it's small it should be fine)
Polymer is fine for the impact head
They want us to use foam for the base
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Instructor comments were to be cautious of the upward angle for the test impact head
Instructor warned against using polymer for the impact head, saying it would absorb too much energy
Try to use a swinger instead of foam for the base
We brought up all these ideas to ATA and they said to continue as we were doing, they want us to use foam and said that a small upward angle of the impact head should be fine
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Haven't obtained feedback yet
Only answered questions last class, we didn't get any relevant suggestions
Risks and Areas of Concern
Fixture plate might be unable to create a high enough first mode to not attenuate the shock
Resources or Information Required but not Available
None, ATA has been very helpful with all resources/information
Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
None spent
$1500 remaining
Must purchase delrin this week (Under $50, doesn't need order form)
Progress on Report and Webpage
Broke up the first part of the report due last Friday between team members
Continuing on the parts of the report due this Friday
