Abstract: The article focuses on the structural design and optimization of the frame of Shell's environmentally friendly marathon electric energy-saving vehicle, in order to achieve the goals of improving racing performance and lightweighting. Based on the requirements of the Shell Environmental Marathon, a first generation edge beam energy-saving racing car frame model is designed using CATIA V5 professional software. By using ANSYS Workbench software for finite element analysis, the stress distribution cloud map and displacement distribution cloud map of the frame under bending, twisting, acceleration, turning, and braking conditions under full load are compared and analyzed to verify its stiffness and strength requirements. And based on the results of the 100th topology optimization iteration, the original frame structure is optimized to obtain the final version of the energy-saving racing car frame model, achieving a weight reduction of 21.4%, providing reference for the design optimization of the frame.
