標準化部材をモジュール構成とした車体構造設計の検討

抄録

As manufacturing has begun to move from mass production to mass customization, manufacturing industries are currently constructing the architecture to provide wide variety of products in countries around the world. Modular design and standardization is effective for mass customization. In recent years, modular design techniques have been researched in vehicle development. Then, car manufacturers have been announcing their own architecture about the car design. We have focused on pipe-based components as the standardized member of body structure. Since the pipe is a general-purpose member, we can get them easily. In this study, we have applied our unique modular design techniques to the rear body structure model as a case study. Firstly, we have calculated the frame layout consist of solid elements by topology optimization. Then, we have replaced the frame layout of the solid elements with the frame layout of the beam elements. Next, we have optimized the design parameters of the standardized member consist of 4 pipes. Finally, we have confirmed that the frame structure made up of standardized members is less than the yield stress.
