Abstract:

The forming simulation, the experimental test, and the structure analysis in combination were applied to study the sheet thinning and the material work hardening in the stamping process of the car body component. It was found that in the forming process, the yield limit increase of the sheet metal demonstrates a more significant effect on the enhancement of the car body component strength than that of sheet thinning on the weakening of the strength. The obtained results provide a more accurate reference for the optimization on the light-weight design of the car body structure.

Key words: vehicle engineering, components strength, stamping process, car body component
