Abstract: To improve the lightweight level of automotive body and solve the internal hot stamping challenges on tailor-welded door ring such as cracking, wrinkling and local distortion, a finite element model of integral hot stamping of a tailor-welded door ring with differential strength and thickness was built. The maximum thinning rate and maximum springback of the door ring were selected as formability indexes, the forming temperature (600–900 ℃), coefficient of friction (0.1–0.5) and stamping speed (50–300 mm/s) were taken as variables, and then the response surface method was used to establish the relationship between the process parameter variables and the formability index. Finally, the multi-objective optimization genetic algorithm was used to obtain the optimal combination of process parameters, which provides theoretical guidance for practical production.
