Design
Projects for Engineering Students that are not participating in the BUV Design
Competition.
a. Cog Belt Final Drive
for 3-wheel BUV
Design final drive for the BUV
using a rubber cog drive belt. Use standard size cogs. Must be low cost
and durable. What should be the drive ratio? Use a world standard belt size. What material is best for cog-belt?
Longest life/durability for best price. How to fasten the Cog wheel to the
driveshaft? Estimate life (operating hours). Cost per
unit? Tooling life? Advantages of laser-cut, waterjet, powder metal, stamping
cog pulleys etc.
b. Rubber Torsion Suspension
for 3-wheel BUV
Develop rubber-torsion
swing arm front suspension that is only 5" wide. and can handle load from
450
lbs to 850 lbs.
c. Powertrain Sourcing Project
for 3-wheel BUV
Research the best
Diesel and Gasoline powertrain options from Asia. Address
engines with integrated CVTs and/or gear boxes. Reliability, ease of
repair, availability of parts, part life, cost, etc? What engine upgrades
(features) are worth the money?
d. Round
Tube Frame Option
for front half of 3-wheel BUV
Round tube is more
available in some countries. Change design from box-tube to round tube. What is the ideal size for the frame? Wall thickness?
Design? Cost?
f.
Water Pump Option for 3-wheel BUV
powered by v-belt. For irrigation or pumping through a water filter.
g. Michelin Tweel
Application for 3 wheel BUV
Work with Michellin
Tire company on a BUV application for the front tire. What is the ideal
tire and rim? For desert/rocks/thorns? jungle/mud/sand?
All-around? Ideal bolt pattern? Cost? Weight? Hardness?
Trial Project?
h. Simulate/Analyze
the 3-wheel BUV Front and side impact
Create simulation of existing BUV suspension and suggest
improvements to make design more robust, lower cost, better performance,
increase safety. Failure Mode
Effects Analysis?
i. LED
Lighting:
What is the low cost
lighting package that ensures vehicle will be seen? What is the
upgrade…a conventional lighting package that allows safe operation at night?
Price? Reliability? Simplicity?
