Abstract：

For 6016 aluminum alloy radiator shell, by analyzing the forming process of part, the finite element simulation of the deep drawing process for part was

conducted by using software Dynaform, and the maximum thinning rate of part was used as the index to evaluate its forming quality. Then, based on the orthogonal test design, the influence laws of blank holder force, friction coefficient, stamping speed and die clearance on the forming quality of part were studied, and based on grey system (GS) theory, the process parameters with high correlation with the maximum thinning rate of part were analyzed, and the central composite design (CCD) was conducted by the response surface method (RAM). Furthermore, the optimal process parameter combination was obtained with the blank holder force of 20.1 kN, the friction coefficient of 0.16, the stamping speed of 1500 mm·s-1, the die clearance of 1.05 mm, and the maximum thinning rate of part was 23.029%.The comparison and analysis between the solid parts made by this scheme and the numerical simulation results show that the numerical simulation analysis results are reliable, which could provide some guidance for the forming of radiator parts.
