Abstract：

To draw a sheet fully is an important premise of a good quality on automotive body surface, which can be valued by the drawing performance of sheet. Several drawing tests of aluminum sheet 6016 from different suppliers were conducted, and a finite element model (FEM) with high precision was built based on the experiment results. Then, the feasibility and reliability of the simulation results were validated, and the influences of major process parameters, such as material, process and die on the drawing properties of aluminum sheet 6016 were studied. The results show that the aluminum sheet drawing performance has a positive correlation with the material parameter n-value, ratio of thickness to diameter t/D and die radius, while a negative correlation with the blank hold force and friction factor. The limited drawing ratio(LDR) of four groups are determined by FEM to design the drawing process and enhance production efficiency.
