Front Suspension Design Final Report Solomon Metcalf Kevin Beckford Daniel Atsyor
Presentation Overview • • • Design Statement Design Specifications Design Concepts Drawings Completed/Uncompleted Task Conclusion
Design Statement • The purpose of this project is to design and build a new front-suspension for Sunsation II.
Prior Design
Improvements • • • Weight Adjustable Wheel Scrub Ride height Braking assembly Shock selection
Design Specification Easy Adjustment; camber, caster, toe-in/out Mounting to honeycomb unibody 6” of total shock travel Little weight Support body weight (=900 -1000 lb)
Budget • • • • Bulk metal (aluminum/iron) Shocks Wheels Tires Hardware (Bolts/Nuts) Steering linkage Steering Box Brake calipers Brake rotors Rotor hubs Brake lines Master cylinder Pedal Assembly 600. 00 1200. 00 1000. 00 300. 00 500. 00 400. 00 700. 00 800. 00 200. 00 250. 00 • Total 7850. 00
Tasks Completed • • WBS Schedule (primavera) Budget Final Design Shock specifications Designing Bulk Head Simulated Drawings Fine tuning suspension geometry to minimize scrub
On-Going Task • Modeling components in Pro-E/Working model 2 -D • Ordering parts/materials • Suspension Calculations

Shock Schematic
Uncompleted Tasks • • • Connecting Suspension All finalized engineering drawings Machining parts Analyzing Performance Stress testing of suspension Suspension performance
Team Improvement • Better organization of work time • Total group involvement
Next Semester Task • • Analyzing material stress/strain Material Selection Ordering parts Machining and assembly Analyzing Performance Stress testing of suspension Suspension Calculations Incorporation of Stirring System
Conclusion • Though the project is behind schedule for most groups on the solar car. We do hope to accomplish our over all goals that were set from the start. • This has also been a stressful but simulating learning experience.
