I designed the 2023 CWRU Motorsports frame which was part of our car that won first place overall at the 2023 Baja SAE Ohio event. Our 2023 frame is very focused on system integration. The suspension in the rear mounts to sleeved holes drilled in the frame and our 4WD chain routes through 3 sleeved tubes on the bottom plane of the car. Our frame is optimized for weight reduction, driver safety and comfort, torsional stiffness while also adhering to 70+ pages of roll cage rules from SAE.
Weight was optimized by calculating tube bending stiffness/strength to optimize the tube diameter, wall thickness and material while complying with the rules.
