MAE 435 – Spring 2015
April 21st, 2015

2. introduction
Formula SAE competition provides the opportunity for students to design, build, and race a formula style racecar
The team placed 37th out of 109 teams in the 2014 competition
The MAE 435 team is responsible for the design of primary component, fabrication of the car, and competition related administrative work

4. DriveR Controls
Needle bearing supports for steering shaft reduced friction while turning.
Pedal box redesign to fit into narrower frame
Shift linkage mechanism modified to correct upshifts and downshifts

5. Intake Runner Lengths Calculated Using Helmholtz resonance theory
𝑅𝑃𝑀=81𝑐 𝐴 𝑅−1 𝐿𝑉 𝑅+1
Material used TI-6061 Aluminum
Large Plenum was designed to provide little flow restriction to the runners.
Flow Analysis allowed us to tweak the design before fabrication.

6. Drivetrain
Gearing calculator used to find optimum gear ratio for acceleration and low top speed of the course
Differential carrier designed for lighter weight while maintaining strength and durability
Tripods, axles, and miscellaneous parts selected for durability and value

7. suspension
Suspension calculator used to determine the camber and camber gain
Push rod suspension selected over pull rod based on the car’s performance
Front upright design changed to decrease weight, rear design changed to accommodate push rod system

8. brakes
Switched to 4 wheel disc brake setup for more control over braking force
Increased rotor size for increased stopping power
Redesigned front and rear carriers to allow for more clearance

9. aerodynamics Custom designed nose cone, sidepods, and diffuser
First CFD aerodynamic analysis completed on an ODU FSAE car
Diffuser increases rear downforce and speeds airflow underneath car through full length
Reshaped the nose and sidepods to decrease drag as much as possible

10. sponsorship Sponsorship presentation created to market team
Sponsorships include Exxon- Mobil and Panda Express

11. budget
Over budget by $4,950.00, but received $4, for a net over budget of $740.00

12. cost report and paperwork
Cost report was submitted on time with great detail
Other paperwork submitted in a timely fashion and approved
High quality posters and presentations for competition in production

13. Testing, training, and competition
Competition is May 13th – 16th
Car will be tested for durability every weekend after April 18th until competition
Competition consists of endurance, autocross, and acceleration events
Drivers will practice on technical sections of course
