| Abstract(E) | This study investigates the integration of rear underbody components in automobiles using cold stamping techniques. Finite Element Method (FEM) simulations revealed the necessity of establishing a strength gradient within a single side member and ensuring adequate energy absorption across the rear components during collision. A unified rear side member structure was developed, utilizing Tailored Welded Blanks (TWB) and patchwork structures with a strength of 1470 MPa. Prototype parts were successfully produced, demonstrating no issues with fracture, wrinkling, or dimensional accuracy, validating the proposed stamping method. FEM simulations confirmed that the new structure offers superior rear impact performance compared to conventional designs. This suggests that component integration via cold stamping could be a viable option in automotive manufacturing. |
