Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Working on vibration model to find natural frequency of system
Finally have all equipment and 3d prints (except modified plunger) to begin testing prototype
Test bed complete, pogo pins attached and wired
Accomplishments from Previous Week
Used higher resolution Instron at Delta Design Thursday to test compression springs and some of the o-rings
Recieved hybrid amplifier Friday
Coated aluminum test bed
Finishing up dynamic model
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Learn amp software, get permissions from ACMS - Jenessa
Figure out how to control amp with labview - Russ
Continue machining - Chris
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
plunger
- discussed different designs/materials
- current plunger will dissapate too much evergy by deflecting
- Sasa suggested possibility of adhering a steel disk to make it rigid?
insulation for pogo pins
-Look into Tufram Omega
-Doesn't flake/chip, betteer than inserts
blowout valve
- considered machining an ambient pressure port without increasing the chamber volume by too much
- Sasa suggested set screws with Teflon tips
- need a better design in the future, but may do a quick one for testing
Ref mic
- ref mic not necessary in every position, just one and then it can be rotated to 3 other positions manually
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Consider making very thin plunger out of aluminum with gussets to prevent flexing
Start testing with whatever equipment available
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Risks and Areas of Concern
Energy loss in piezo system
- piezo is so small that it's completely enclosed, so it will be hard to see what's going on
Ordering correct piezo and having sufficient time with it for testing before quarter ends
Resources or Information Required but not Available
Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
Anodizing - free! (Thanks A-Z Metal Finishing)
>$4000 remaining
Progress on Report and Webpage
New drawings and figures
