| Abstract: | Considering the springback of 5182 aluminum alloy wind beam as the research object, the real stress-strain curves of 5182 aluminum alloy sheet under different rolling directions and strain rates were obtained through one-way tensile test, and introduced into the numerical simulation mode. The influence of sheet metal forming speed, die clearance, and friction coefficient on the springback of 5182 aluminum alloy windshield beams was studied and the formation mechanisms were analyzed. According to the response surface method, the prediction model of 5182 aluminum alloy windshield beam springback was established. The prediction model was verified by experiments under different conditions. The research provides a new method for the analysis of aluminum alloy sheet springback. |
