Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The top ring of the baskets have been cut off in order to bend the lip outwards to 31"
We have extended our baskets to 31" (from 30" previously) by bending 3/16" stainless steel rods into a 31" ring
These rings will be ready to be weld onto the baskets
Aluminum support rods have been successfully attached to the bottom cross bar and is ready to be weld
1/4" aluminum rods that will be used to hold each basket into place on the support rods have been cut to size (34") and ready to weld
The team has decided to buy a heavy duty maintenance free lazy susan bearing that will withstand heavy moments placed onto it when the cart is being tilted for transportation into the trucks
Accomplishments from Previous Week
Fabrication of the parts have been accomplished
All remaining parts needed (wheels, screws, nuts, washers, lazy susan) have been ordered
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Re-dimension base plate of the cart to attach on casters and the new lazy susan bearing (Annie)
Finish making 31" rings to prepare them for welding onto the baskets (Yuji)
Maximize basket separation dimensioning on SolidWorks to reduce height of cart before drilling holes into the support poles (Kelli)
Figure out how to implement brake mechanism onto the cart (Jonathan)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Last week we gave a mini presentation to our sponsors as well as the staff and lab supervisors at CAEP. Everyone was in favor of our spinning design and were very excited to see the whole cart in person.
Sponsors had no worries about the design, but told us that the conveyor washer cannot hold carts that weigh about 300 lbs and over.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Emphasized analysis of our brake mechanism (weight the mass should be, the angle, and how fast the cart must move to activate the brake)
2 or 4 brakes wouldn't make a big difference
Look into tilting industry standards
Suggested rubber or delrin as brake material - easily replaceable material
Cables are fine to use
Suggested using squares as support, rather than round poles
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
NA
Risks and Areas of Concern
Cart with maximum amount of components placed inside should not exceed the maximum load capacity of the conveyor washer
Resources or Information Required but not Available
What is the best material to use as brakes that goes into high temperature washes
Coating sprays that we can use to coat our iron and steel lazy susan bearing
Schedule
We hope to have the cart built by next week so that it is ready to be weld together
Update Gantt chart.
Budget (list amount spent and amount remaining)
Amount spent (this week) = 769.45
Amount remaining (as of today 2/27) = 532.71
Progress on Report and Webpage
Report has been updated with respect to instructor and TA comments, Webpage is scheduled to be updated on thursday (2/28)
Report has been sent to Team SurfUp for review.
