The safety margin of FSAE (Formula Student Automobile Equation) racing car should be lager. To meet the requirements of strength and stiffness, fully tap the potential for lightweight frame.This paper optimized topology design and section size of car frame in the SIMP method with the finite element analysis software. Considering the mesh of model remains unchanged and simulating three track actual conditions by the size of optimization method, we change the model parameter values,and the corresponding maximum deformation of car’s frame decreases by 7%, 7.5%, 14.7% respectively under the certain strengh and stiffness of car’s frame. When the maximum stress was less than 200MPa, the quality of the frame was reduced by 32%. Finally, through the modal analysis and test, optimization design of frame could effectively avoid the coupling effect and external excitation, the eight around the ring tesr time could be reduced by 3%. The racing car frame achieveed the purpose of light weight.
