Abstract: The purpose of optimizing the frame structure design of electric energy saving vehicle is mainly to improve energy saving and environmental protection by lightweight. The frame model for lightweighting design is established according to the Shell Eco-marathon race rules. The ANSYS Composite Prep/Post composite material module is applied to study the frame of aluminum honeycomb panels, and the displacement and stress distribution of the frame baseplate are obtained through static analysis. Altair Inspire is adopted to obtain the overall driving situations of frame under different working conditions. Based on the above results, the optimum structural design of the frame is conducted. The article introduces the application of composite aluminum honeycomb panels in fuel-efficient vehicles, provides reference value for the feasibility of composite materials in this aspect.
