Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Belt-drive chosen over friction-drive system to increase torque output of stationary rider
Design reciprocating pump attachment based on OX-1 but should also be able to attach to any bike
Determine optimum gear ratio to implement on OX-1
Accomplishments from Previous Week
Proof of concept testing for OX-1 biking up 8% grade hill with minimum payload; top speed trials for single speed bike
CAD of bike stand and water pump attachment
Matlab simulation for reciprocating water pump (sponsor's desired pump choice)
Preliminary belt-drive research: V-belt vs. flat belt vs. synchronous belt, UV resistant material to use for protective cover, number of pulleys to implement
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Design belt-drive system (choose optimal gear ratio), build model and test - Dennis, Derek, Jamie
Design water pump attachment mechanism
Generate needed parts list and start ordering materials
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Meeting in person 4/11/17
Water pump design should be simplistic, long lasting, with optimal gpm and pumping depth
Action: Perform optimization calculations and model different pumps to determine best option
Water filter should be long lasting, easy to replace, only used to filter drinking water
Action: Use 2 filters; one for sediment on intake to increase lifetime of pump; one for bacteria on outtake that is removable
Clarification of project scope and design objective
Action: Perform optimization calculations to meet...
32 ft depth minimum for reliable pumping
3 gpm of water minimum
12 mph travel speed minimum
Implementation of power generation while riding to address energy aspect of project
Action: Design bike attachment to be compatible with water pump and alternator/generator (energy generation = secondary objective)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Design Proposal Presentation in class 4/12/17
Always use metric units
Action: Remember for future calculations and presentations
Keep opportunity for energy generation/storage open as a secondary objective
Action: Design bike attachment to be compatible with both pump and alternator
Verify water filtration capabilities and maybe implement more than one filter
Action: Do some more research on water sources in Africa and life of filtration systems
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Design Proposal Presentation in class 4/12/17
Water filter lifetime may not be as long as advertised if water being filtered is from a river or stream
Possible to filter out bacteria with only one filter?
Could look into heat treatment for further water purification
Risks and Areas of Concern
Biking up 8% grade hill with required payload and single speed bike
Implementing belt drive system within tight space constraint of bike frame and stand
Resources or Information Required but not Available
Schedule
