CAD Model of Moonbuggy Design

Honors Project

ME 262

Spring Semester 2001

IUPUI Moonbuggy Design

Senior Design Project advised by Dr. Pidaparti

Purpose is to race in Huntsville, AL on moonlike terrain

Moonbuggy team recently went to compete and placed 11th/28 teams.

Requirements for Moonbuggy

Must be work of students Must be human powered Unassembled, must fit in a volume of four foot

cube Riders must always be 15” above ground Turning radius must be 20’ or less Must have one male, one female driver

Conclusion

What did we learn? How did this go above and beyond the normal

course duties? What are our future plans for these 3D

models?

What did we learn?

How to create solid models in Pro/Engineer How to assemble solid models in Pro/Engineer Real World Applications of Joints Composition of Suspension and Transmission

System

How Did this go beyond normal course work?

We used Pro/Engineer to model systems We studied in three dimensions We did an in-depth study of Moonbuggy

components

What are the future plans for the models?

Motion studies of joints Motion studies of linkages Motion studies of reactions to applied loads
