156B Week 6
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Analysis: Completed analysis about buoyancy, Solidworks analysis of buoy, preliminary analysis on power consumption
Design: Design completed for all hardware. Design remaining: Plumbing and wiring
Test: Tom and Isaiah has completed pressure chamber for us to test prototype anytime, which will greatly reduce our expenses.
Accomplishments from Previous Week
Solidwork Analysis for buoy assembly about material strength and buckling of current design was done
Modified Bulkhead design, particularly modifying hole positions to reduce risk of breaking material in fabrication.
Pumps, valves, and bladder were obtained from sponsor
Finalized decision to use 20 D cells Ni-MH for batteries.
Electronic tray in queue for 3D printer
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Continue Fabrication (Whole Team)
Complete plumbing design (Mike)
Complete Bulkhead and CPVC tube fabrication (Gary, Austin, Mike)
Start Internal Housing Fabrication (James)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Approved final design (meeting 5/3)
We will use pumps and valves rated at 50psi for this quarter (meeting 5/3)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Dr Tustaniwskyj commented that CTD Sensor Mounting on pipe wall would result in stress concentration. (Presentation 5/2) Sponsor showed monitoring vessel currently in use with the same mounting method, and assured us that risk is minimal.
Risks and Areas of Concern
Programming CTD sensor to integrate with phone is difficult
Resources or Information Required but not Available
