Our ME 262 Honors Project Objectives

• Learn to use the CAD/CAM software ProE
• Study the components of the Moonbuggy
• Create 3D models of parts of the moonbuggy
• Combine the part models with other students
  models
• Present final results

14

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?

32
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

33
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

34
What are the future plans for the models?

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