Abstract：

In order to eliminate cracking defects of front door reinforcing plate parts produced by 6016 aluminum alloy, the analysis model was established, and the influences of the drawbead strength, the friction coefficient on mold surface and the blank holder force on the forming properties of aluminum alloy material were determined. Then, the order of primary and secondary factors and the better combination of parameters influencing the forming factors were obtained by the orthogonal experiment method. The results show that the blank holder force has the greatest influence on the cracking of parts, followed by the friction coefficient on mold surface, and the least influence is the equivalent drawbead strength. The obtained debugging parameter combination is the equivalent drawbead strength of 66.0 N·mm-1, the blank holder force of 950 kN, and the friction coefficient on mold surface of 0.17. The experiments show that the simulation results have a better consistency with the actual production results, and the numerical simulation can reduce the uncertainty of aluminum alloy parts in debugging process and the debugging cost.
