156B Week 8
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
detailed CAD assembly created and updated to include updated bearing blocks
simplified design to only use 12 mm bearings
use 12 mm shaft on the precessing frame as well
created animation of detailed CAD model
bearing blocks in process of being assembled
Accomplishments from Previous Week
redesigned bearing blocks
created drawing and began machining bearing blocks
updated CAD assembly with new bearing blocks
created CAD animation
redesigned support for precession frame to use 12mm shaft and began machining this component
Goals for Next Week (list names after each item). Use specific and measurable objectives.
have a completed gyroscope prototype - Aki, KC, Cross
bearing block - KC and Cross
precession support component - Aki
finish updated draft of report and webpage - Steven
update CAD if necessary - Steven
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
5/15/18 - Prasad said we do not need to worry about sensors since there is so little time left to work on the project
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
5/16/18 - James and Professor Delson approved of our updated bearings design
5/16/18 - wanted us to simplify design so that we could use just one bearing block for each rotating part
actions taken: we simplified the design as suggested
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
none
Risks and Areas of Concern
friction in rotational elements
vibrations in supporting pole
need clearance holes for shafts
12 mm shaft might not be strong enough to support the weight of the entire gyroscope
not much time left to finish
will we be able to spin the gyrowheel fast enough without using a motor?
Resources or Information Required but not Available
none
Schedule
Describe upcoming milestone
finish a complete prototype by next week
Update Gantt chart.
Budget (list amount spent and amount remaining)
have spent approximately $900
we have a flexible $1000 budget; Prasad said the actual budget is around $2000
Progress on Report and Webpage
rough draft of report and webpage completed
complete updated draft of report and webpage by this Friday in response to instructor and TA comments
