Based on the stiffness and vibration modal analysis for a FSC racing car frame with the FEA method and testing evaluation, the design parameters of optimal tubular space frame were determined through the sensitivity analysis. Oriented the minimizing the frame weight, the thickness of tubes was conducted under meet the requirements of stiffness and vibration modal. As a result, the frame weight was deceased by 7.18 %.
