Abstract
As carbon neutrality is the advancement in the electric vehicle industry, the demands for battery module cases are increasing. However, current manufacturing machineries are encountering challenges to meet the required demand owing to low precision and long duration for cutting the materials. To meet the demand, it is necessary to study a machine tool that has machining precision and reduced cutting process time. However, current machine tools are not optimized because they are designed according to the subjective decision and experience of the designer. To solve this problem, research is needed to lightweight and increase stiffness by optimally designing ribs of machine tools. In this study, I attempted to increase stiffness and lightweight by applying the topology optimization technique to the column rib of the machine tool. Furthermore, I intend to derive the optimized design parameters by comparing static stiffness of the initial shape and optimized shape after optimization.
