ADVISOR: HO-HOON LEE

2. Initial Design Factors
SAE Rules
Compliance with driver safety regulations
Drivetrain Team
Provide surface for motor mount
Room requirements for power train
Suspension Team
Provide strong enough mounting structure for Arms and Shocks
Steering Team
Provide clearance and mounting surface for Rack & Pinion steering

3. Safety Factor Maximum Repeating Force: Sn’ = Sn*Cm*Cs*Cr*Cst N = 2
Sn’ = 96.7 MPa
Sn’/N = MPa
Sn’ = Sn*Cm*Cs*Cr*Cst N = 2
where:
Sn = Endurance Limit = MPa
Cm = Material Factor = 1.0
Cst = Stress-Type Factor = .8
Cr = Reliability Factor = .75
Cs = Size Factor = .85

4. Material Selection 4130 Steel Alloy fits within our design window.
Provides ease of welding & good impact resistance
Yield stress of 460 MPa
Excellent Strength/Weight Ratio
Material of choice for SAE Baja

5. Since Last Semester Improved previous design
Material size changed to 1” OD x .12” Wall (SAE Standard)
Implemented new design software (AutoCAD)
