Structure Optimization Design for the Frame Of Electric Vehicle

Frame structure design, an important part of vehicle assembly, is crucial in automotive design. In order to further optimize the performance of frame and to make the vehicle lighter and more efficient, this paper expounds the topology optimization design method in detail with a multi-function electric vehicle as the research object by adopting ANSYS to analyze. The overall performance of the frame and material utilization are improved by the optimization. This result shows that this method can acquire the optimal distribution of material while improving the structure and properties of materials as well as can reduce the structural weight and cut design cost. The method can also be widely applied to other bearing structural optimization design projects.
